Can You Own a Python in Oregon? What State and Federal Law Actually Allow

If you’re picturing a ball python curled up in a terrarium, the answer to whether you can own a python in Oregon is usually yes. But the moment you’re talking about a Burmese python, reticulated python, or anything large enough to make the local news, the legal picture shifts fast — and it involves three separate layers of government that rarely get mentioned together.

Oregon doesn’t regulate pythons the way it regulates lions or bears. Instead, snake ownership sits at the intersection of state wildlife rules, a decades-old federal law originally written for weasels and mongooses, and county ordinances that can be stricter than anything the state requires. Here’s how those layers actually apply if you’re keeping, buying, or thinking about buying a python in Oregon.

Is It Legal to Own a Python in Oregon

Most common pet pythons, including ball pythons (Python regius), are legal to own in Oregon without a special permit. That’s because Oregon’s primary “exotic animal” statute doesn’t cover snakes at all. An “exotic animal” for purposes of that section means a member of the family Felidae not indigenous to Oregon, any nonhuman primate, any nonwolf member of the family Canidae not indigenous to Oregon, any bear except the black bear, and any member of the order Crocodylia. Pythons simply aren’t on that list.

That doesn’t mean pythons are unregulated, though. A separate branch of state law puts certain reptiles under the authority of the Oregon Department of Fish and Wildlife (ODFW) rather than the Department of Agriculture. As ODFW’s Rick Boatner explained to a Portland news outlet, there are classifications under Oregon statutes that have animals exempt from rules, prohibited species, controlled species and noncontrolled species. Where a python species falls in that system determines whether you can legally keep it. For a broader look at what else slithers around the state legally, the native snakes found throughout Oregon offer useful context on how the state treats reptiles generally.

Pro Tip: Before buying or rehoming any python in Oregon, check the species against ODFW’s reptile classifications first — the answer can differ dramatically between a ball python and a Burmese python even though both are “just pythons” to a new owner.

Federal Law: The Lacey Act and “Injurious” Python Species

Even if Oregon said nothing about pythons at all, federal law would still apply. The U.S. Fish and Wildlife Service uses the Lacey Act to designate certain species as “injurious wildlife,” a status that restricts how they cross state and national borders. This process happened in stages for large constrictor snakes.

In 2012, the agency finalized a rule covering four species. The Fish and Wildlife Service amended its regulations under the Lacey Act to add Python molurus, which includes Burmese python and Indian python, Northern African python, Southern African python, and yellow anaconda to the list of injurious reptiles, prohibiting importation into the United States and interstate transportation of any live animal, gamete, viable egg, or hybrid of these species except by permit for zoological, education, medical, or scientific purposes. That rule took effect in March 2012.

Three years later, the agency expanded the list again. The Service added reticulated python, DeSchauensee’s anaconda, green anaconda, and Beni anaconda to the list of injurious wildlife, effective April 2015. Notably, the agency withdrew its proposal to add the boa constrictor to the list of injurious wildlife — meaning boas escaped federal injurious-species status even though several python species did not.

Practically speaking, this means you generally can’t ship a Burmese python or reticulated python across state lines, even to rehome it, without a federal permit. It doesn’t automatically make possession illegal within Oregon, but it does complicate breeding, selling, and relocating these snakes if you already own one. For background on one of the most frequently discussed injurious species, see this detailed profile of the Burmese python.

Which Python Species Are Restricted or Banned in Oregon

Oregon layers its own state-level restrictions on top of the federal injurious species list. ODFW maintains rules around what it calls “reptiles of concern.” The regulations include a ban on capturing, keeping, possessing, transporting, or exhibiting venomous reptiles or reptiles of concern — listed python species, green anaconda, Nile monitor, and other reptiles designated by the commission as a conditional or prohibited species. In other words, Oregon didn’t just adopt the federal list; it built a parallel state list that specifically calls out python species by name.

The good news for existing owners is that Oregon didn’t strip permits retroactively. Persons who hold pre-July 1, 2010 permits for these species may legally possess the species for the remainder of the reptile’s life. That grandfather clause means someone who legally acquired and permitted a restricted python before mid-2010 isn’t forced to give it up, but no new permits have been issued for these species since that cutoff.

Python Species	Federal Lacey Act Status	Oregon State Status
Ball python (Python regius)	Not listed as injurious	Generally legal, no special permit
Burmese python	Injurious since 2012	Reptile of concern; new permits not issued
Reticulated python	Injurious since 2015	Reptile of concern; new permits not issued
Northern/Southern African python	Injurious since 2012	Reptile of concern; new permits not issued
Boa constrictor	Proposal withdrawn; not injurious	Generally legal statewide, but see county rules

Common carpet pythons, ball pythons, and other smaller species that don’t appear on either the federal or state restricted lists remain widely kept as pets across Oregon without triggering these permit rules.

Permit Requirements for Owning a Python in Oregon

Because snakes fall outside the Department of Agriculture’s exotic-animal statute, you won’t apply for a python permit through that agency. Instead, any permitting for restricted reptiles runs through ODFW. No person may keep exotic wildlife without first receiving a permit from the wildlife commission when a species falls into a controlled or prohibited category.

For python species on the reptiles-of-concern list, though, the practical reality is that new permits simply aren’t being granted. The only path to lawful possession of a restricted python today is holding a permit issued before the July 1, 2010 cutoff. If you’re considering a species that isn’t restricted at all, such as a ball python or corn snake, no ODFW or ODA permit is required in the first place — ordinary purchase and care standards apply.

• Non-restricted pythons (ball pythons, most carpet pythons): No state permit needed
• Reptiles-of-concern pythons (Burmese, reticulated, African species): Only lawful with a pre-July 2010 ODFW permit
• New acquisitions of restricted species: Not currently permittable in Oregon

Size and Length Restrictions in Oregon

Oregon doesn’t set a single statewide length limit that applies to every python. Instead, size restrictions tend to show up at the county level, and they can be strict enough to override what state law would otherwise allow. Multnomah County is the clearest example.

Multnomah County prohibits snakes that are eight or more feet long, so Portlanders can’t have a boa, according to Boatner. That same length threshold applies to large pythons, meaning a Burmese python or reticulated python that reaches typical adult size would run afoul of the county rule even if you somehow held a grandfathered state permit for the species. Since many popular large-bodied constrictors can exceed eight feet as adults, this local rule functions as a practical size cap for anyone living within Multnomah County’s boundaries, including Portland.

Local Ordinances That May Apply in Oregon

State law explicitly leaves room for cities and counties to go further than Salem does. Notwithstanding the provisions of ORS chapters 496, 497 and 498 relating to wildlife, and ORS 609.305 to 609.335 relating to exotic animals, a city or county may prohibit by ordinance the keeping of wildlife and may prohibit by ordinance the keeping of exotic animals. That means a python that’s technically legal under state and federal law could still be banned outright in a specific city or county.

Multnomah County again illustrates this. Multnomah County has a “blanket ‘no venomous snake’ rule,” Boatner noted — making it the only Oregon county with that particular prohibition. Pair that with the county’s eight-foot length limit, and Portland-area residents face tighter python restrictions than someone living in a rural county with no local wildlife ordinance at all. If you’re weighing where large reptiles fit into an urban environment, it’s worth comparing this to how Portland handles other wildlife and pet regulations, such as its approach to urban squirrel populations or its citywide leash requirements for dogs — both examples of how local rules routinely layer on top of state baselines.

Important Note: Because ordinances vary by city and county and can change, always confirm current rules directly with your local county clerk or animal control office before acquiring a python, even one that’s legal under state and federal law.

It’s also worth remembering that Oregon’s wildlife agencies regulate far more than reptiles. ODFW oversight extends to native amphibians and other herpetofauna, including the state’s native frog species and salamanders found throughout the state, which fall under different protections than the exotic reptiles discussed here but are handled by the same agency.

Penalties for Illegally Owning a Python in Oregon

Keeping a restricted python without a valid pre-2010 permit, or violating a local size or venomous-species ordinance, exposes an owner to real legal risk rather than a simple warning. Oregon’s exotic-animal violations have historically been treated as misdemeanor offenses, and unlawfully possessed wildlife is subject to seizure by state authorities regardless of how the animal was acquired.

Beyond the legal penalty itself, ODFW and county animal control agencies have the authority to confiscate an illegally kept python. That’s a meaningful risk for anyone who inherits, buys secondhand, or transports a restricted species without confirming its status first — especially since federal Lacey Act violations for illegal interstate transport carry their own separate enforcement track from state wildlife violations. Given how a single python can trigger federal, state, and county rules simultaneously, verifying legality at all three levels before bringing one home is the only way to avoid an expensive and stressful surprise. If venomous reptiles are part of your broader interest in Oregon wildlife risk, the state’s venomous species guide covers how those separate — and often stricter — rules work.

The bottom line: a ball python bought from a reputable Oregon breeder is unlikely to raise any legal questions at all. A Burmese or reticulated python is a different story entirely, layered with federal transport restrictions, a closed state permit system, and county-level size and venomous-species bans that can apply even when state and federal law would otherwise allow the animal. Checking all three levels before you buy is the only way to know where you actually stand.
