The Mayo or Yoreme are an indigenous group in Mexico, living in the northern states of southern Sonora, northern Sinaloa and small settlements in Durango.[1]

Mayo people originally lived near the Mayo River and Fuerte River valleys.[1] The Mayo sustain themselves mainly by agriculture and fishing, but also create artwork and crafts.

In their own language they call themselves Yoreme.[2][3] The term Mayo means "the people of the river bank" and comes from the Mayo River.[1]

The Mayo language belongs to the Cahita branch of the Uto-Aztecan language family.[1] It is closely related to Yaqui and it is spoken by approximately 40,000 people (Ethnologue 1995 census).

They own traditional authorities, who are elected by vote and their hierarchy is respected on par with the Mexican civil laws.
