If you have ever wondered whether you could legally keep a lion in New Mexico, the short answer is no — and the legal barriers come from multiple directions at once. Both state and federal law prohibit private lion ownership, and some New Mexico cities layer on additional restrictions of their own.
Understanding exactly why it is prohibited — and what consequences come with ignoring those rules — matters whether you are simply curious, researching exotic animal law, or trying to understand what options exist for legitimate wildlife facilities. This article walks through every layer of the law that applies to lion ownership in New Mexico.
Is It Legal to Own a Lion in New Mexico?
You cannot keep big cats, crocodiles, alligators, primates, or wolves in New Mexico. Lions fall squarely within that prohibition. New Mexico prohibits private ownership of certain exotic animals without specific authorization, and the New Mexico Department of Game and Fish (NMDGF) enforces these restrictions under the state’s Wildlife Conservation Act.
Lions are classified as Group IV animals under New Mexico’s importation framework — and it is not just lions. Nearly every wild cat is listed as a Group IV species, meaning servals, panthers, cheetahs, and ocelots are all illegal to own in New Mexico. That classification effectively closes the door for any private resident hoping to keep a lion as a pet or backyard animal.
Beyond state law, a separate and powerful federal statute — the Big Cat Public Safety Act — adds another layer of prohibition that applies nationwide, including in New Mexico. Both frameworks must be understood together to get the full picture.
Key Insight: Even if you believe a legal loophole exists at the state level, federal law independently bans private lion possession. Complying with one layer of law while violating the other still results in criminal liability.
What Federal Law Says About Lion Ownership
The Big Cat Public Safety Act was enacted December 20, 2022, to end the private ownership of big cats as pets and prohibit exhibitors from allowing public contact with big cats, including cubs. This law changed the legal landscape for lion ownership across every state, including those that previously had weak or no restrictions.
The Big Cat Public Safety Act makes it illegal to privately possess or breed big cats. Signed into law December 20, 2022, it places new restrictions on the commerce, breeding, possession, and use of certain big cat species within the U.S. The law refers to big cats as “prohibited wildlife species” and includes the following species and hybrids: lion, tiger, leopard, snow leopard, clouded leopard, jaguar, cheetah, and cougar.
The African lion (Panthera leo) is explicitly named in the Act. It placed new restrictions on the commerce, breeding, possession, and use of certain big cat species. This means you cannot buy, sell, breed, transport across state lines, or privately possess a lion anywhere in the United States — regardless of what any individual state’s law says.
The law provides for exceptions for some federal, state, and privately owned facilities such as zoos, universities, and sanctuaries that have big cats, but these exceptions do not apply to private individuals. If you are not operating an accredited zoo, a USDA-licensed facility, or a qualified wildlife sanctuary, no exception applies to you.
A limited grandfather provision existed for people who already owned big cats before the law’s enactment. The BCPSA bans the future sale, purchase, and breeding of big cats for private ownership. However, it “grandfathers in” individuals who already legally owned big cats before the law was enacted, allowing them to keep the animals they currently possess, provided they registered them with the U.S. Fish & Wildlife Service and adhere to strict new regulations banning breeding and public contact. That registration window closed on June 18, 2023, and is no longer available.
The Act also intersects with the Endangered Species Act. Most big cats are listed as either endangered or threatened under the Endangered Species Act, and take — meaning harassing, harming, pursuing, hunting, shooting, wounding, killing, trapping, capturing, or collecting — of such species and their offspring is prohibited, with limited exceptions for take authorized by statute, regulation, or permit. This creates a second independent federal prohibition on top of the BCPSA.

New Mexico’s Laws on Owning a Lion
At the state level, New Mexico uses an importation classification system administered by the NMDGF. The New Mexico Department of Game and Fish maintains a 27-page list of animals that are legal and illegal to own. Animals are placed into one of four importation groups: Group I for semi-domesticated animals not requiring a permit; Group II for live non-domesticated animals not known to be invasive or dangerous; Group III for animals presenting minimal or manageable concerns that require specific provisions before an importation permit is issued.
Lions are Group IV animals — and it is not just tigers. Nearly every wild cat is listed as a Group IV species on the list. Group IV designation means the animal is prohibited entirely; no importation permit is available for private individuals seeking to own one.
It is against the law in New Mexico to own felines, crocodiles, wolves, alligators, and primates. This prohibition is not limited to lions — the entire family of big cats is off-limits for private residents. Owning exotic animals in New Mexico comes with strict regulations designed to protect both the public and native wildlife. The state has specific laws governing which species can be kept, how they must be housed, and what permits are required. These rules help prevent ecological harm, ensure animal welfare, and reduce risks associated with dangerous or invasive species.
New Mexico’s exotic pet framework also interacts with the state’s health regulations. Under NMSA 1978 § 77-18-1, the sale, purchase, trade, and possession with intent to keep as a pet of any subhuman primate, skunk, raccoon, fox, or other sylvatic carnivore may be regulated by the Department of Health for the protection of public health and safety. Lions, as large wild carnivores, fall within the scope of this regulatory authority as well.

Permits and Requirements for Lion Ownership in New Mexico
Because lions are classified as Group IV animals under New Mexico’s importation rules, no private possession permit exists for them. The permit framework in New Mexico is designed for species in Groups I through III — not for animals whose possession is outright prohibited.
For species that do qualify for permits, the process is rigorous. New Mexico requires permits for individuals and organizations seeking to own certain exotic animals. The NMDGF oversees this process, which varies based on species and purpose. Applicants must justify ownership by detailing housing, veterinary care, and contingency plans for escapes or emergencies.
Personal possession permits are the most difficult to obtain due to public safety and animal welfare concerns. Educational and exhibition permits, granted to zoos, wildlife sanctuaries, and research institutions, require compliance with federal laws such as the Animal Welfare Act. Even these institutional permits would not authorize private residential ownership of a lion.
Importing any exotic animal into New Mexico adds another layer of requirements. Bringing exotic animals into New Mexico requires an Importation Permit from the NMDGF. Applicants must submit documentation on the species’ origin, health records, and intended destination. The state assesses potential risks, including disease transmission and ecological impact, before granting approval.
New Mexico also mandates a Certificate of Veterinary Inspection (CVI) for imported exotic animals to verify they are free from contagious diseases. For permitted facilities — not private owners — enclosure and transport requirements are equally strict. Exotic animals must be housed in secure enclosures that prevent escape and minimize stress. Dangerous species, such as large carnivores or venomous reptiles, may require double enclosures or trained handlers.
Important Note: No permit pathway exists for a private New Mexico resident to legally own a lion. The permit system applies to accredited institutions, zoos, and licensed exhibitors — not individuals keeping lions as personal animals.
Educational and exhibition permits, granted to zoos, wildlife sanctuaries, and research institutions, require compliance with federal laws such as the Animal Welfare Act. Facilities must demonstrate adequate enclosures, trained staff, and veterinary oversight before approval. Private residents do not qualify under this framework.

Local Laws That May Apply in New Mexico
State law sets the baseline, but New Mexico cities and counties can — and often do — go further. Local restrictions can also exist in accordance with city or municipal ordinances. This means that even if you were somehow navigating state-level restrictions, local law could independently prohibit lion ownership in your city or county.
Elephant Butte, New Mexico, offers a clear example of how municipal codes treat big cats. No person shall keep any animal that is considered exotic in the state or which is wild, fierce, dangerous, venomous, noxious, or naturally inclined to do harm, including but not limited to carnivores such as tigers, lions, jaguars, cougars, bobcats, lynx, cheetahs, leopards, and all other wild cats, except where a proper and valid city wild and exotic animal permit is obtained and adequate protective devices are provided to prevent the animals from escaping or injuring the public.
Even in municipalities that issue wild and exotic animal permits, those permits typically require that the animal be housed in a licensed facility — not a private home. While your state may allow you to keep certain animals as pets, local laws can restrict ownership. State laws are frequently changing in response to concerns for public safety and animal well-being. You should always double-check for any new or proposed state or local legislation.
The practical takeaway: before assuming any gap exists between state and local law, contact your city or county government directly. Many New Mexico municipalities have adopted ordinances that mirror or exceed state-level prohibitions on dangerous exotic animals.

Penalties for Illegally Owning a Lion in New Mexico
The consequences for illegally possessing a lion in New Mexico come from multiple enforcement frameworks — state wildlife law, the BCPSA, and potentially the Endangered Species Act — and they stack.
At the state level, the NMDGF is the primary enforcement body. The NMDGF serves as the primary enforcement agency for New Mexico’s exotic animal laws. Officers have the authority to inspect properties, issue citations, and seize unlawfully possessed animals. They collaborate with local law enforcement and federal agencies like the U.S. Fish and Wildlife Service when cases involve interstate transport or sale of prohibited species.
For illegal possession of a Group IV animal, New Mexico law treats the violation as a misdemeanor criminal offense. If someone is caught with a Group IV animal in their home, it is a full misdemeanor crime — you could serve up to 364 days in jail and pay up to a $1,000 fine. That is the penalty for a single violation.
The penalties escalate with repeat offenses or more serious conduct. Under New Mexico Statutes Annotated 17-2-46, illegal possession of wildlife can result in misdemeanor charges, with fines of up to $1,000 per violation and jail time of up to six months. More severe penalties apply for trafficking, breeding, or intentional release of prohibited species. Repeat offenders or those involved in large-scale illegal operations could face felony charges, particularly if their actions cause ecological damage or harm individuals.
Courts may also impose restitution payments for environmental or public safety costs. This means the financial exposure goes beyond the statutory fine — you could be ordered to pay for any damage your animal caused to native wildlife, property, or the emergency response triggered by an escape.
Federal penalties under the BCPSA add another dimension. The BCPSA makes it unlawful to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce, or in a manner substantially affecting interstate or foreign commerce, or breed or possess prohibited wildlife species — including lions, tigers, leopards, snow leopards, clouded leopards, jaguars, cheetahs, and cougars, or any hybrids thereof. Federal violations carry their own fines and imprisonment terms, separate from state charges.
Important Note: State and federal charges are not mutually exclusive. A single incident involving an illegally possessed lion in New Mexico could result in simultaneous prosecution under state wildlife law, the Big Cat Public Safety Act, and the Endangered Species Act.
Beyond criminal exposure, allowing untrained people to maintain big cats in their homes not only harms animals, it threatens public safety. Lions, tigers, and other big cats are powerful animals who can easily kill or severely injure humans. Private ownership of big cats endangers those living in the neighborhood, as well as first responders who are ill-equipped to handle situations where an animal has escaped.
The bottom line is straightforward: owning a lion in New Mexico is prohibited at the state level, banned at the federal level, and further restricted by many local ordinances. The legal risk — criminal charges, fines, animal seizure, and civil liability — is substantial. If your interest in big cats is genuine, supporting accredited sanctuaries and wildlife organizations or visiting USFWS-recognized facilities are the lawful ways to engage with these animals.
