A cock is the male of any type of domestic fowl, and cockfighting is a blood sport in which two (or more) cocks are placed in a ring or confined area and encouraged to attack or fight each other. Cockfighting is illegal in all 50 states and the District of Columbia—but remains legal in Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands.

Although cockfighting is illegal in all states, the potential punishment for the crime varies from state to state. In thirteen states, a first offense charge of cockfighting is a misdemeanor—including Alabama, California, Hawaii, Kentucky, Louisiana, Mississippi, New Mexico, Ohio, South Carolina, South Dakota, Tennessee, Utah, and West Virginia. But in California, Louisiana, and New Mexico, second, third, and subsequent offenses may be prosecuted as felonies.

And some states also prohibit possession of cockfighting tools (implements) such as a gaff or slasher; ownership and training of cocks for the purpose of cockfighting; and attending cockfighting events.
Cockfighting laws are generally located in a state’s statutes—and usually in the state’s penal or criminal code.

In Alaska (AK), cockfighting is illegal and considered a serious offense. The state's laws prohibit not only engaging in cockfighting but also the possession of birds for fighting, possession of cockfighting implements, and being a spectator at a cockfight. These prohibitions are outlined in Alaska's criminal statutes. Specifically, under Alaska Statute § 11.61.140, it is a class A misdemeanor to knowingly attend an animal fighting event, and under § 11.61.145, it is a class C felony to cause, sponsor, arrange, hold or participate in an animal fighting event. The severity of the penalties reflects the state's commitment to animal welfare and the prevention of animal cruelty. Repeat offenses and involvement in cockfighting activities can lead to more severe charges and penalties, including potential felony charges for certain acts related to cockfighting.
