The Opata (, /ˈopata/) are an Indigenous peoples in Mexico. Opata territory, the “Opatería” in Spanish, encompasses the mountainous northeast and central part of the state of Sonora, extending to near the border with the United States. Historically, they included several subtribes, including the Eudeve, Teguima, and Jova peoples. Most Opatan towns were situated in river valleys and had an economy based on irrigated agriculture. They spoke the Opata language, a Uto-Aztecan language, that is now extinct. In the 16th century, at the time of Spanish contact, the Opata were the most numerous people in Sonora. Some sources indicate that as an identifiable ethnic group, the Opata are now extinct, or nearly extinct. Today, some people identify as Opatas. Language The Opata language was a Uto-Aztecan language, related to neighboring languages such as O'odham, Tarahumara, Tepehuan, Yaqui and Mayo, among others. The Eudeve dialect is called Dohema. The Tehuimas spoke Tehuima, and the Jovas spoke Jova. The Eudeve and Tehuima languages were closely related, as "different as Portuguese and Spanish." Jova was a more distinct language.<ref>Johnson, Jean B. "The Opata: An Inland Tribe of Sonora." in The North Mexican Frontier, ed. by Basil C. Hedrick, J. Charles Kelly, and Carroll L. Riley.

During the 1993 census in Mexico, 12 persons claimed to be “Opata” speakers, but this is widely considered to be an error in the census count. Professor Manuel García Madrid, an Opata from Sonora, has published a linguistic text on the Tehuima dialect. American linguistic anthropologist David L. Shaul has done extensive research and published much material on the Eudeve dialect. Field anthropologist Campbell Pennington researched and published much information on the Opatan peoples and their dialects during the latter part of their history. Name As the three Opatan groups lived adjacent to one another, Franciscan missionaries had by about 1800 lumped them together into one group they called "Opata." Several Franciscan missionary records and subsequent anthropological accounts state that “Opata” was borrowed from a Pima Indian word meaning “enemy,” the name allegedly given by the northern and southern Piman peoples to their Opatan neighbors. However, according to Opatan oral traditionalists, “Opata” is the name some Tehuima villages gave to themselves and means “iron people,” since iron ore was abundant in Opata territory, and
