A casino is a gambling establishment, a building or large room where people can play games of chance for money or other prizes. Casino games include poker, blackjack, roulette, baccarat, and craps. Most casinos have rules and regulations regarding gambling. Some have minimum bets or maximum payouts. A casino may also offer comps (complimentary items or services) to players.

Casinos are found worldwide and are operated by governments, private companies, or charitable organizations. Some are located on Indian reservations and are exempt from state laws. In the United States, casinos are most commonly operated in Atlantic City, New Jersey, Las Vegas, Nevada, and on American Indian reservations. Some casinos are also located in cruise ships, land-based resorts, and hotel complexes.

The precise origin of gambling is unknown, but it is widely believed to have evolved from a variety of social activities. Gambling in some form or another has been popular throughout history, from Mesopotamia, ancient Greece, and China, to Napoleonic France, Elizabethan England, and the United States.
