Californios are Hispanic Californians, especially those descended from Spanish and Mexican settlers of the 17th through 19th centuries. California's Spanish-speaking community has resided there since 1683 and is made up of varying Spanish and Mexican origins, including criollos, Mestizos, Indigenous Californian peoples, and small numbers of Mulatos. Alongside the Tejanos of Texas and Neomexicanos of New Mexico and Colorado, Californios are part of the larger Spanish-American/Mexican-American/Hispano community of the United States, which has inhabited the American Southwest and the West Coast since the 16th century. Some may also identify as Chicanos, a term that came about in the 1960s.

In Hispanic America, criollo is a term used originally to describe people of full Spanish descent born in the viceroyalties. In different Latin American countries, the word has come to have different meanings, mostly referring to the local-born majority.
