Can You Own a Chimpanzee in Wyoming? What State and Federal Law Say

Can you own a chimpanzee in Wyoming? The honest answer is more complicated than a simple yes or no. Wyoming is one of a shrinking number of states without a specific statute banning private possession of great apes, but that gap in the law does not mean the door is wide open.

Nationwide, Connecticut and 30 other states already prohibit private possession of some or all primate species as pets, according to Friends of Animals. Wyoming sits in a smaller group of states that leaves the question mostly unaddressed at the statutory level. This guide walks through what state law actually says, how federal rules fill in the gaps, what permits you would realistically need, and why a city ordinance or homeowners association rule could still shut the idea down before you ever bring an animal home.

Is It Legal to Own a Chimpanzee in Wyoming

The chimpanzee (Pan troglodytes) is not mentioned anywhere in Wyoming’s statute books. According to the Animal Legal & Historical Center, Wyoming has no law that restricts possession or use of a great ape by any person or entity. That places the state in stark contrast to the majority of the country, where primate ownership is either banned outright or tightly permitted.

That silence in the law is not the same as a green light, though. It typically means county and municipal governments, along with federal wildlife rules, end up doing the regulating that the state legislature never got around to. If you are weighing this decision, it helps to compare it with Wyoming’s approach to other dangerous animals in Wyoming, many of which face similarly patchwork oversight rather than a single clear statute.

It is worth noting that the same regulatory gray area applies to other exotic species people sometimes consider as pets. Wyoming’s treatment of raccoons, for example, follows a comparable pattern of state silence paired with local restriction, which you can see in more detail in this breakdown of whether it’s legal to own a raccoon in Wyoming.

Important Note: The absence of a state ban does not mean unrestricted ownership. Federal wildlife law, county rules, city ordinances, and even your neighborhood’s deed covenants can each independently prohibit keeping a chimpanzee, regardless of what Wyoming’s state code does or does not say.

What Federal Law Currently Says About Primate Ownership

At the federal level, the picture is almost as permissive as Wyoming’s, at least for now. Per the Animal Welfare Institute, aside from the ban on importing primates for the pet trade, there are no federal laws governing the sale or keeping of primates as pets. In other words, you cannot legally bring a chimpanzee into the country to keep as a pet, but once an animal is already in the domestic breeding pipeline, federal law currently does little to stop it from changing hands.

That changed somewhat in 2015, when regulators closed a long-standing loophole that had treated wild and captive chimpanzees differently under federal protection. As the Association of Zoos and Aquariums notes, recent progress for primates includes the ending of the split listing for chimpanzees in the Endangered Species Act. That means every chimpanzee in the United States, whether born in a research facility, a roadside zoo, or a private home, now carries endangered species protections that can require a federal permit for certain interstate transfers or sales. This is closely related to how endangered animals in Wyoming are treated under overlapping state and federal frameworks.

The bigger federal development to watch is the Captive Primate Safety Act (CPSA). The bill would amend the Lacey Act, and according to the Animal Welfare Institute, it would amend the Lacey Act to prohibit the private possession of nonhuman primates such as chimpanzees, galagos, gibbons, gorillas, lemurs, lorises, monkeys, orangutans, and tarsiers. Current owners would not automatically lose their animals; the same source explains that private citizens would be allowed to keep pet primates they currently own but would be required to register their animals so first responders and animal control officers know a wild animal is present in the home.

This is not a new idea. The House actually passed an earlier version by a wide margin years ago: on 23 February 2009 the House voted 323 to 95 in favor of the bill, though it never became law. Lawmakers reintroduced the CPSA again in 2025, drawing an explicit comparison to an earlier success story. Sponsor Mike Quigley pointed to his prior legislation as a model, noting that his Big Cat Public Safety Act banned the private ownership and breeding of big cats including lions, tigers, and pumas after being signed into law in 2022.

Key Insight: The Captive Primate Safety Act is not currently law. Until Congress passes it, federal policy leaves chimpanzee ownership largely to individual states, which is exactly why Wyoming’s silence on the issue matters so much.

Wyoming’s Laws on Owning a Chimpanzee

Digging into Wyoming’s actual statute language confirms just how little the state has addressed this. Beyond the absence of a great ape law, Wyoming does not even have a state endangered species provision providing additional state protection for endangered or threatened species. Most states with primate restrictions built them into either their exotic animal codes or their endangered species statutes. Wyoming has neither, which leaves federal law as the primary safety net for a species like the chimpanzee.

The state’s general wildlife code defines “exotic species” narrowly. Under Wyoming statute, exotic species means any wild animals, including amphibians, reptiles, mollusks, crustaceans or birds not found in a wild, free or unconfined status in Wyoming. Mammals like chimpanzees are not specifically listed in that definition, which is part of why the Wyoming Game and Fish Department’s authority over primates is murkier than its authority over, say, an exotic reptile or bird. This same regulatory ambiguity shows up in how the state treats other unconventional pets, including the framework covered in this guide to hedgehog ownership laws in Wyoming.

Wyoming’s animal cruelty statute still applies regardless of the ownership gap. According to the Animal Legal & Historical Center, the state’s cruelty law is broad enough to include great apes, and notably, there are no exceptions under the cruelty law for scientific research or testing. So even if you could legally acquire a chimpanzee under Wyoming’s silence on ownership, you would still be fully bound by the state’s cruelty statute in how you house, feed, and care for it. Similar baseline welfare obligations show up across Wyoming’s animal statutes, including the requirements covered in this overview of goat ownership laws in Wyoming.

Legal Layer	What It Covers	Chimpanzee Ownership Status
Wyoming state statute	Wildlife, exotic species, cruelty code	No explicit ban or license requirement
Federal law (current)	Import ban, Endangered Species Act	No import for pet trade; ESA permits may apply to transfers
Federal law (proposed)	Captive Primate Safety Act	Would ban new private ownership if passed; existing owners grandfathered
City and county ordinances	Local animal control codes	Varies widely; several cities ban outright

Permits and Requirements for Chimpanzee Ownership in Wyoming

Even where state law is quiet, Wyoming still runs a general permitting system for live wildlife that anyone considering an exotic animal should understand. The state’s own guidance is direct: prior to importing, possessing, or transporting live wildlife in Wyoming, a permit is required, and all applicable regulations must be reviewed before attempting to possess wildlife in the state, since a permit will not be issued for certain prohibited species. The Wyoming Game and Fish Department is not the only agency involved, either. Per the department’s own reference materials, the Wyoming Livestock Board, Wyoming Department of Health, United States Fish and Wildlife Service, counties, municipalities and subdivisions have enacted further rules and regulations pertaining to the possession of wildlife.

In practice, that means anyone pursuing chimpanzee ownership in Wyoming would need to work through several layers at once: a state import/possession review from the Game and Fish Department, likely a USDA exhibitor’s or dealer’s license under the Animal Welfare Act if the animal is used commercially, and a federal Endangered Species Act permit for many types of interstate transfer given the chimpanzee’s protected status. None of these processes are designed with pet ownership in mind, which is a major reason so few private individuals successfully navigate them. Wyoming’s permit-based model shows up in other corners of its animal code too, including the state’s approach to beekeeping laws in Wyoming, where local certification and compliance requirements layer on top of a permissive state framework.

Pro Tip: Before assuming a permit path exists, call the Wyoming Game and Fish Department, the county clerk’s office where you live, and the U.S. Fish and Wildlife Service’s endangered species permit office. Get each answer in writing. A verbal “probably fine” from one agency does not protect you from another agency’s rules.

Local Laws That May Apply in Wyoming

This is where Wyoming’s lack of a state ban tends to run into a wall. Wyoming Game and Fish Department materials make the point directly: while the department may allow the possession or importation of various wildlife species, local laws, ordinances, and covenants may be more restrictive, and it is your responsibility to comply with all local laws, ordinances and covenants before importing or possessing live wildlife.

Cheyenne is a clear example. City code states that no person shall own any wild or exotic animal within the city limits, except that this restriction shall not apply to the keeping of small cagebirds or aquatic, amphibian or nonpoisonous reptilian animals or small rodents such as hamsters, guinea pigs or gerbils kept solely as pets, according to Cheyenne’s municipal code. A chimpanzee would fall squarely under that “wild or exotic animal” prohibition. Laramie takes an even more specific approach, stating plainly that wild animals, exotic pets, primates, and venomous reptiles are not allowed within city limits.

Jurisdiction	Primate/Exotic Animal Rule
Cheyenne	Bans wild or exotic animal ownership citywide, with narrow exceptions for small caged pets
Laramie	Explicitly bans primates, wild animals, exotic pets, and venomous reptiles
Unincorporated counties	Often no specific ordinance, but state permit rules and HOA covenants may still apply

Wyoming’s pattern of letting cities set stricter rules than the state is not unique to primates. It mirrors how the state handles breed-specific restrictions in its municipalities, a comparison worth reviewing alongside pit bull laws in Wyoming, where several towns have adopted their own species or breed bans independent of state statute. Homeowners associations add one more layer on top of city and county rules; even in a jurisdiction with no animal ordinance at all, a deed covenant can prohibit exotic pets outright, so it pays to check your specific address rather than assume a neighbor’s situation applies to you too.

Penalties for Illegally Owning a Chimpanzee in Wyoming

Because Wyoming has no dedicated chimpanzee statute, “illegal ownership” in this state almost always traces back to violating one of the other legal layers rather than a single state law against apes. A Cheyenne or Laramie resident who brings home a chimpanzee in violation of a city ordinance can expect the animal to be treated as a code violation, which typically opens the door to citations, fines, and a mandated removal of the animal from city limits. Chimpanzee bites and attacks also raise the same liability questions that apply to any powerful animal kept privately, an issue explored further in this look at dog bite laws in Wyoming and how negligence and strict liability standards can extend to owners of unconventional or dangerous pets.

Federal exposure is real even without a Wyoming-specific ban. Endangered Species Act enforcement has led to real citations elsewhere in the country for people who acquired protected apes without the required paperwork; in one reported case, a Connecticut man was cited for owning an endangered ape and faced a fine of less than $500, though penalties can run far higher depending on the violation and whether commerce across state lines was involved. Importing a primate in violation of the federal pet-trade ban can also trigger Lacey Act penalties, which range from confiscation of the animal to significant fines and, in serious cases, criminal charges.

Common Mistake: Assuming that because Wyoming’s state code says nothing about chimpanzees, no government agency can act against you. In reality, a city ordinance violation, a missing federal endangered species permit, or a Lacey Act import violation can each result in penalties completely independent of what Wyoming’s legislature has or has not written into law.

If the Captive Primate Safety Act eventually passes, the penalty landscape would shift again, since new private ownership would become a federal violation nationwide regardless of state law, while existing, registered owners would likely be grandfathered in. Until then, anyone in Wyoming weighing this decision needs to treat the absence of a state ban as the beginning of the research process, not the end of it, and confirm the rules at the city, county, and federal level before acquiring an animal that size, strength, and intelligence make genuinely difficult to keep safely in a private home.
