Multiracial people are people of more than one race. A variety of terms have been used both historically and presently for mixed race people in a variety of contexts, including multiethnic, polyethnic, occasionally bi-ethnic, Métis, Muwallad, Colored, Dougla, half-caste, ʻafakasi, mestizo, mutt, Melungeon, quadroon, octoroon, sambo/zambo, Eurasian, hapa, hāfu, Garifuna, pardo, and Gurans. A number of these terms are now considered offensive, in addition to those that were initially coined for pejorative use.

Individuals of mixed-race backgrounds make up a significant portion of the population in many parts of the world. In North America, studies have found that the mixed race population is continuing to grow. In many countries of Latin America, mestizos make up the majority of the population and in some others also mulattoes. In the Caribbean, mixed race people officially make up the majority of the population in the Dominican Republic (73%), Aruba (68%), and Cuba (51%).
