The official flag of New Mexico, a subnational polity of the United States, consists of a red sun symbol of the Zia people on a field of gold (yellow). It was officially adopted in 1925 to highlight the state's Native American and Hispano heritage: It combines a symbol of the Puebloan people, who have ancient roots in the state, with the colors of the flag of Spain, which established and ruled Nuevo México for over two and a half centuries.

The Zia or Tsʾíiyʾamʾé are an indigenous nation centered at Zia Pueblo (Tsi'ya), a Native American reservation in the U.S. state of New Mexico. The Zia are known for their pottery and use of the sun symbol. They are one of the Keres Pueblo peoples and speak the Eastern Keres language.
