Afro-Mexicans, also known as Black Mexicans, are Mexicans who have heritage from sub-Saharan Africa and identify as such. As a single population, Afro-Mexicans include individuals descended from both free and enslaved Africans who arrived to Mexico during the colonial era, as well as post-independence migrants. This population includes Afro-descended people from neighboring English, French, and Spanish-speaking countries of the Caribbean and Central America, descendants of enslaved Africans in Mexico and those from the Deep South during Slavery in the United States, and to a lesser extent recent migrants directly from Africa. Today, there are localized communities in Mexico with significant although not predominant African ancestry. These are mostly concentrated in specific communities, including the populations of the Oaxaca, Huetamo, Lázaro Cárdenas, Guerrero, and Veracruz states.

The Costa Region or Costa Chica lies on the Pacific coast of the state of Oaxaca, Mexico, south of the more mountainous Sierra Sur inland from the coast. It includes the districts of Jamiltepec, Juquila and Pochutla.
