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 New Jersey, cockfighting is strictly prohibited under state law. It is considered animal cruelty, which is a criminal offense. New Jersey's statutes classify cockfighting as a third-degree crime under N.J.S.A. 4:22-24, which includes causing, allowing, or permitting any animal fight. Additionally, possession of cockfighting implements, owning or training cocks for fighting, and attending events related to cockfighting are also illegal. Penalties for engaging in or being associated with cockfighting activities can include fines, imprisonment, and other legal consequences. As a third-degree crime, those convicted could face a term of imprisonment of 3 to 5 years, a fine of up to $15,000, or both. New Jersey's strong stance against animal cruelty reflects the seriousness with which the state treats offenses related to cockfighting.
