The Seris are an indigenous group of the Mexican state of Sonora. The majority reside on the Seri communal property (Spanish, ejido), in the towns of Punta Chueca (Seri Socáaix) and El Desemboque (Seri Haxöl Iihom) on the mainland coast of the Gulf of California. Tiburón Island (Tahéjöc) and San Esteban Island (Coftéecöl and sometimes Hast) were part of their traditional territory, but some Seris also lived in various places on the mainland.
