Yoloxóchitl Mixtec is one of the many Mixtec languages that belong to the Mixtecan branch of Oto-Manguean. Yoloxóchitl Mixtec is spoken in four villages along the Pacific Coast of southern Guerrero, Mexico. The greatest linguistic vitality is found in the villages of Yoloxóchitl (pop. approx. 3,000) and Arroyo Cumiapa (pop. approx. 1,500) about 6.5 miles to the northeast of Yoloxóchitl. In both of these villages almost all speakers are highly fluent. Yoloxóchitl Mixtec is also spoken, though rapidly disappearing, in Cuanacaxtitlan (pop. approx. 4,000) and Buenavista and its surrounding farms (pop. approx. 5,000).
