	The Lordship of Oñate (Basque: "Oñatiko jaurreria", Spanish: "Señorío de Oñate") was one of the Basque "señoríos", and represented a period of feudal rule in a region surrounding the city of Oñati, in the present-day province of Gipuzkoa, Basque Country. The lordship was ruled by a single family, the House of Guevara (in Basque, "Gebara"), who all hailed from the town with the same name in Álava. Their titles as "Lords of Oñati" were first conferred by the monarchs of Navarre, as the Lordship acted as a vassal state of the former. Circa the year 1200 the Lordship was conquered and annexed by the Kingdom of Castile, but it was maintained until the year 1845, when Oñati was incorporated into the province of Gipuzkoa and the title was lost.
