Nebraska’s mix of shortgrass prairie, sandhill dunes, river bluffs, and eastern deciduous woodland supports one of the richer snake communities in the central Great Plains. Nebraska is home to 29 different snake species — 25 that are non-venomous and 4 that are venomous. Some species live statewide, while others are confined to a handful of southeastern counties along the Missouri River.
This guide covers 28 types of snakes in Nebraska, from the state’s largest constrictor to its smallest and rarest rattlesnake. Each entry notes where the species tends to turn up, how it behaves, and the field marks that separate it from its lookalikes.
Important Note: Only four snakes native to Nebraska are venomous, and all four are pit vipers. If you are bitten by a snake you cannot identify, treat it as a medical emergency, keep the affected limb still, and get to a hospital rather than attempting home remedies.

1. Prairie rattlesnake
The prairie rattlesnake (Crotalus viridis) is the most common venomous snake found in Nebraska, with a range that spans roughly the western half of the state, preferring short and mixed-grass prairies with rocky outcrops or canyons. It favors prairie dog towns, grass prairie, and rocky outcrops and typically measures between three and five feet long.
Coloration runs through all shades of brown, green, and gray-green with darker blotches on their back, which helps the snake disappear into dry grass. Anyone curious how this species compares to its relatives elsewhere can see the broader picture in this breakdown of how many types of rattlesnakes exist across North America.
2. Western massasauga
At 18 to 39 inches long, the western massasauga (Sistrurus catenatus) is the smallest rattlesnake in Nebraska. It carries gray and brown coloring with dark, round brown blotches on the back, light and dark bands on the tail, and two narrow white lines circling a dark brown band along the side of the head.
This species is restricted to a small corner of the state; a Game and Parks wildlife specialist once noted “it’s really just found in seven counties in southeast Nebraska.” Habitat loss from converting wet prairies to cropland has hurt the crayfish populations the massasauga depends on for shelter. Iowa shares this same threatened species along its border, and the snakes found in Iowa include several of the same wetland specialists.
3. Timber rattlesnake
The timber rattlesnake (Crotalus horridus) is Nebraska’s largest rattlesnake, reaching up to 60 inches in total length, though it averages 44 to 50 inches. It shows a tan, gold, or light brown color with black cross bands and a reddish-brown dorsal stripe running from behind the head toward the black-tipped tail.
In Nebraska, this species survives only in the far southeast portions of the state, in the southern parts of Jefferson, Gage, and Pawnee counties and along the limestone bluffs of the Missouri River. It is a Tier I Species of Greatest Conservation Need, listed as critically imperiled, and its population has been declining to fewer than 1,000 individuals since 2005. The species’ range extends east into states like Arkansas, where you can compare notes in this guide to the snakes of Arkansas.
4. Copperhead
The copperhead (Agkistrodon contortrix) is the fourth of Nebraska’s venomous residents, and it has the tightest range of any of them. It is limited mainly to the state’s southeastern counties along the Missouri River. Like the other pit vipers on this list, copperheads are protected from indiscriminate killing under state wildlife statutes, a topic covered in more depth in this overview of snake removal laws in Nebraska.
Coppery, hourglass-shaped crossbands over a tan or pinkish body make this species fairly easy to pick out once you know the pattern. Copperheads are far more numerous in states like South Carolina, where encounters are a regular part of the state’s snake population.
5. Bullsnake
The bullsnake (Pituophis catenifer sayi) is a heavyweight among the non-venomous types of snakes in Nebraska. This is Nebraska’s largest snake, and specimens are commonly reported statewide. A Nebraska Game and Parks education specialist pointed out that bullsnakes have a bad reputation for aggression, but their only defense mechanism is to move quickly or bite; they are common throughout the state and a big part of the ecosystem.
Common Mistake: Many people confuse bullsnakes for rattlesnakes because of similar blotched coloring. Bullsnakes have round pupils, no rattle, and no heat-sensing pits, and they will often hiss and vibrate their tail against dry leaves to mimic a rattle when startled.
Bullsnakes are powerful constrictors that feed heavily on pocket gophers and ground squirrels, which makes them valuable allies for farmers. The related gopher snake complex also turns up farther west; readers interested in that overlap can check the snake species found in Utah.
6. Great Plains ratsnake
The Great Plains ratsnake (Pantherophis emoryi) is usually a light brown or grayish snake with blotches down the back, a smaller series of blotches on the sides that alternate with the back markings, and a creamy white belly with a checkerboard pattern. Adults typically measure 28 to 46 inches long.
This species favors limestone outcroppings in open grasslands, avoiding densely wooded areas but using hillsides and canyons with occasional woody cover. In Nebraska, it is found in the southeast and in central counties that border Kansas, only around 15 miles north of the state line. Ratsnakes in this genus show up across much of the southern Plains, including the populations detailed in this guide to snakes native to Alabama.
7. Western fox snake
The western fox snake (Pantherophis ramspotti) is a heavy-bodied constrictor with dark brown or reddish blotches over a yellowish-tan background, often mistaken for a rattlesnake because it vibrates its tail when alarmed. In Nebraska, this species occupies the eastern edge of the state, favoring river bottoms, prairie edges, and agricultural fencerows where rodents are plentiful.
Fox snakes get their common name from a musky odor they release when handled, which some people think smells like a fox’s den. They are strong swimmers and climbers, and a cornered fox snake will often strike repeatedly even though it has no venom to back up the bluff.
8. Black rat snake
The black rat snake (Pantherophis obsoletus) is a large, glossy constrictor that turns almost entirely black as it matures, though juveniles show a blotched pattern closer to the Great Plains ratsnake. In Nebraska, this species is restricted to wooded bluffs and timber along the far eastern edge of the state near the Missouri River.
Black rat snakes are excellent climbers and will raid tree cavities and barn lofts for birds, eggs, and rodents. States farther east, such as the populations covered in this guide to snakes in Connecticut, host the same species at the eastern end of its range.
9. Common garter snake
The common garter snake (Thamnophis sirtalis) is one of the most frequently seen types of snakes in Nebraska, found in yards, parks, and wetlands statewide. It carries three light stripes, one down the center of the back and one along each side, set against a dark olive, brown, or black background.
Garter snakes give live birth rather than laying eggs, and a single female can produce a few dozen young in a single litter. Their diet leans heavily on earthworms, amphibians, and small fish, and readers who want the full picture of this group can explore the different types of garter snakes found across the country.
10. Plains garter snake
The plains garter snake (Thamnophis radix) looks similar to its common cousin but usually shows a brighter orange or yellow stripe down the back, bordered by dark checkered blotches on the sides. It prefers grasslands, wet meadows, and pond edges across most of Nebraska.
This species is an opportunistic hunter that will take frogs, toads, and tadpoles whenever it finds them near water. For readers curious about the amphibian prey base that sustains Nebraska’s garter snakes, the frog species found in Nebraska make up a significant part of the diet.
11. Red-sided garter snake
The red-sided garter snake (Thamnophis sirtalis parietalis) is technically a subspecies of the common garter snake, but its bold red or orange bars between the black side blotches make it visually distinct enough that most field guides list it separately. This is the subspecies most often seen in the northern and central parts of Nebraska.
Red-sided garter snakes are famous elsewhere for forming massive communal dens that house thousands of individuals during hibernation, though Nebraska’s populations tend to overwinter in smaller groups within rock crevices and rodent burrows. They are harmless to humans and will typically flee rather than bite when disturbed.
12. Western plains hog-nosed snake
The western plains hog-nosed snake (Heterodon nasicus) is named for its distinctly upturned, shovel-like snout, which it uses to dig for toads buried in sandy soil. Plains hog-nosed snakes are part of the broader hognose group found across Nebraska’s western and central regions.
This species puts on one of the most dramatic defensive displays of any Nebraska snake: it flattens its neck like a cobra, hisses loudly, and if that fails, flips onto its back and plays dead with its mouth hanging open. Despite the theatrics, it is mildly venomous only to its toad prey and poses no real danger to people.
13. Eastern hog-nosed snake
The eastern hog-nosed snake (Heterodon platirhinos) shares the same upturned snout and theatrical bluffing behavior as its western relative, but it occupies a different part of the state. This species is associated with eastern Nebraska, where sandy soils support the toad populations it specializes in hunting.
Coloration in this species is highly variable, ranging from solid black or gray to strongly blotched patterns in brown, olive, or orange. A complete regional rundown of hognose distribution and other eastern species appears in this regional snake guide.
14. Eastern yellow-bellied racer
The eastern yellow-bellied racer (Coluber constrictor flaviventris) is a slender, fast-moving snake with smooth scales, a plain olive, tan, or bluish-gray back, and a pale yellow belly that gives the subspecies its name. It is a diurnal hunter that relies on speed and sharp eyesight rather than ambush tactics.
Racers are active foragers that chase down insects, small rodents, frogs, and even other snakes across Nebraska’s grasslands and open woodland edges. Unlike constrictors, they simply pin prey with their body weight and swallow it while still subduing it.
15. Coachwhip
The coachwhip (Masticophis flagellum) is a long, whip-thin snake whose braided-looking scale pattern resembles a woven leather whip, especially toward the tail. In Nebraska, this species sits at the northern edge of its range and is uncommon, typically found in sandy prairie and rangeland in the southwestern part of the state.
Coachwhips are among the fastest snakes in North America and will flee at high speed rather than stand their ground when approached. This same species ranges much farther south into arid landscapes, including the populations found across Mexico’s diverse snake fauna.
16. Eastern glossy snake
The eastern glossy snake (Arizona elegans) is a pale, smooth-scaled burrower with a sheen that gives the species its common name. Its light tan or cream background is marked with faint brown or gray blotches, and it spends most of its time underground or beneath surface debris.
In Nebraska, this species reaches the far northeastern edge of its overall range and is considered uncommon, favoring sandy soils where it can burrow easily in search of lizards and small rodents. Because it is nocturnal and secretive, most Nebraskans never encounter one despite its presence in suitable habitat.
17. Speckled kingsnake
The speckled kingsnake (Lampropeltis holbrooki) is a shiny, dark snake covered in small yellow or white flecks on nearly every scale, earning it the nickname “salt-and-pepper snake.” The speckled kingsnake is one of several species on Nebraska’s list of protected snakes, which limits take and harassment under state law.
Kingsnakes are immune to the venom of the pit vipers they share habitat with and will readily eat copperheads and young rattlesnakes alongside rodents and other prey. Readers interested in the broader kingsnake and milk snake family can see how the group compares in this guide to the different types of milk snakes.
18. Prairie kingsnake
The prairie kingsnake (Lampropeltis calligaster) is a more muted relative of the speckled kingsnake, typically tan or light brown with faint, dull blotches that can be hard to see in bright light. Like the speckled kingsnake, the prairie kingsnake is included on Nebraska’s protected species list.
This species spends much of its life underground or beneath flat rocks and debris, surfacing mainly at dusk to hunt rodents, lizards, and other snakes. Its secretive habits mean population estimates in Nebraska remain limited, which is part of why conservation protections apply statewide.
19. Eastern milk snake
The eastern milk snake (Lampropeltis triangulum) is a classic example of mimicry in the snake world, wearing red or reddish-brown saddles outlined in black over a cream or gray body that can fool people into thinking it is a venomous coral snake relative. In Nebraska, this species occupies wooded river valleys and rocky hillsides in the eastern half of the state.
Milk snakes get their misleading common name from an old myth that they milk cows, which has no basis in fact since they are strict predators of rodents, other snakes, and the occasional bird egg. For a closer look at how this pattern compares across related species, see this guide to the different types of milk snakes.
20. Smooth green snake
The smooth green snake (Opheodrys vernalis) is a slender, bright grass-green snake with smooth scales and a pale yellow or white belly, making it one of the more strikingly colored types of snakes in Nebraska. It favors moist meadows, prairie edges, and grassy roadsides across the eastern and central parts of the state.
This species feeds almost exclusively on insects and spiders, which it hunts by day among tall grass and low shrubs. Its green color fades to blue or gray shortly after death, a quirk that has confused many people trying to identify dead specimens found along roadways.
21. Prairie ring-necked snake
The prairie ring-necked snake (Diadophis punctatus arnyi) is a small, secretive species with a smooth slate-gray or olive back and a vivid yellow-orange ring around the neck that gives the species its name. The belly matches the neck ring in color and often deepens toward the tail.
These snakes spend most of their lives hidden under rocks, logs, and leaf litter, rarely growing past 15 inches long. When threatened, a ring-necked snake will sometimes coil its tail into a tight spiral to display the bright underside as a startle tactic rather than attempting to bite.
22. Brown snake (DeKay’s)
DeKay’s brown snake (Storeria dekayi) is a small, plain grayish-brown snake with two faint rows of dark spots running down the back and a light stripe between them. It is one of the more common snakes to show up in suburban yards, gardens, and even city parks in eastern Nebraska.
This species feeds almost entirely on slugs, snails, and earthworms, which makes it a genuinely useful neighbor for gardeners dealing with pest mollusks. Similar small brown snakes turn up in older urban centers along the East Coast, including the populations discussed in this guide to snakes found in Delaware.
23. Red-bellied snake
The red-bellied snake (Storeria occipitomaculata) is a close relative of DeKay’s brown snake, sharing a similar small size and secretive habits but distinguished by a bright red, orange, or occasionally gray belly. The back is usually brown, gray, or nearly black.
This species favors moist woodland leaf litter and the edges of wetlands, where it hunts slugs and earthworms almost exclusively. Red-bellied snakes rarely exceed ten inches in length and are so docile that most people never realize one has been living under a backyard log pile.
24. Northern water snake
The northern water snake (Nerodia sipedon) is a heavy-bodied, non-venomous snake frequently mistaken for a cottonmouth, even though cottonmouths do not occur in Nebraska. Its background color ranges from gray to reddish-brown with dark crossbands that often darken and become harder to see as the snake ages.
This species is rarely far from permanent water, including rivers, ponds, and reservoirs across much of eastern and central Nebraska. Northern water snakes are aggressive when cornered and will bite readily, though the bite carries no venom and poses no serious medical risk beyond minor bleeding.
25. Plain-bellied water snake
The plain-bellied water snake (Nerodia erythrogaster) is named for its solid yellow, orange, or cream belly, which lacks the blotching seen on the northern water snake. The back is typically a uniform olive, brown, or gray with little to no pattern in adults.
This species favors slow-moving streams, oxbow lakes, and marshy backwaters in the southeastern part of the state. Like other Nerodia species, it feeds heavily on fish and amphibians, and similar water snake populations appear in the wetlands covered in this guide to Arkansas snake species.
26. Diamondback water snake
The diamondback water snake (Nerodia rhombifer) is the largest water snake likely to be found in Nebraska, recognizable by the dark, net-like diamond pattern that crosses its olive or brown back. It can grow considerably heavier-bodied than the state’s other water snakes.
This species sticks close to the Missouri and Platte River systems in the southeastern corner of the state, where it basks on overhanging branches before dropping into the water when disturbed. Diamondback water snakes are powerful swimmers and feed mainly on fish, catfish included, which they often catch at night.
27. Lined snake
The lined snake (Tropidoclonion lineatum) is a small grassland species that closely resembles a miniature garter snake, with a pale central stripe running down a gray or brown back. A double row of dark half-moon markings along the belly helps separate it from true garter snakes.
Lined snakes are found in prairie remnants, vacant lots, and grassy edges across eastern and central Nebraska, often hiding beneath flat rocks or debris during the day. Earthworms make up the bulk of their diet, and like garter snakes, females give birth to live young rather than laying eggs.
28. Western worm snake
The western worm snake (Carphophis vermis) is one of Nebraska’s smallest and least-seen snakes, with a smooth, glossy purple-brown back and a bright pink or salmon-colored belly that extends partway up the sides. This species is included on Nebraska’s list of protected snakes, reflecting how limited and localized its populations are in the state.
Worm snakes spend nearly their entire lives underground or beneath logs and leaf litter in moist, wooded southeastern Nebraska, rarely surfacing except after heavy rain. Their diet consists almost entirely of earthworms, which they locate using a sharp, pointed tail they press against the soil while burrowing.
Conclusion
Nebraska’s snake community reflects the state’s position at the meeting point of eastern woodland, western shortgrass prairie, and Great Plains sandhills. The result is a list that ranges from a critically imperiled timber rattlesnake clinging to a few southeastern counties to a common garter snake that turns up in nearly every backyard.
Most encounters with any of these 28 types of snakes in Nebraska end the same way: the snake retreats, and the person walks away with a story. Rattlesnake numbers in the state are small and declining enough that several species now carry threatened status, which makes leaving snakes alone, rather than killing them on sight, the better choice for Nebraska’s ecosystems and for the people who study them.
