Juan de Oñate y Salazar (Spanish: [ˈxwan de oˈɲate]; 1550–1626) was a Spanish conquistador from New Spain, explorer, and colonial governor of the province of Santa Fe de Nuevo México in the viceroyalty of New Spain. He led early Spanish expeditions to the Great Plains and Lower Colorado River Valley, encountering numerous indigenous tribes in their homelands there. Oñate founded settlements in the province, now in the Southwestern United States.
