Bullfighting is a physical contest that involves a bullfighter attempting to subdue, immobilize, or kill a bull, usually according to a set of rules, guidelines, or cultural expectations.

A bullfighter is a performer in the activity of bullfighting. Torero or toureiro, both from Latin taurarius, are the Spanish and Portuguese words for bullfighter, and describe all the performers in the activity of bullfighting as practised in Spain, Portugal, Mexico, Peru, France, Colombia, Ecuador, Venezuela and other countries influenced by Portuguese and Spanish culture. The main performer and leader of the entourage in a bullfight, and who finally kills the bull, is addressed as maestro (master), or with the formal title matador de toros. The other bullfighters in the entourage are called subalternos and their suits are embroidered in silver as opposed to the matador's gold. They include the picadores, rejoneadores, and banderilleros.
