Otomi (; Spanish: Otomí ) is a group of closely related indigenous languages of Mexico, spoken by approximately 240,000 indigenous Otomi people in the central altiplano region of Mexico. It belongs to the Oto-Pamean branch of the Oto-Manguean language family. It is a dialect continuum of closely related languages, because many of the varieties are not mutually intelligible. The word Hñähñu has been proposed as an endonym, but since it represents the usage of a single dialect it has not gained wide currency. Linguists have classified the modern dialects into three dialect areas: the Northwestern dialects spoken in Querétaro, Hidalgo and Guanajuato; the Southwestern dialects spoken in the State of Mexico; and the Eastern dialects spoken in the highlands of Veracruz, Puebla, and eastern Hidalgo and in villages in Tlaxcala and Mexico states.
