The province of Gipuzkoa (Spanish: Guipúzcoa), in the Basque Country, Spain, is divided into regions known as comarcas (Basque: eskualdeak). These divisions are primarily defined by the local topography and follow the valleys formed by the province's main rivers: the Bidasoa, Oiartzun, Urumea, Oria, Urola, and Deba.
While the Basque Statistics Institute (Eustat) officially groups the municipalities into seven statistical regions (Bajo Bidasoa, Bajo Deba, Alto Deba, Donostialdea, Goierri, Tolosaldea, and Urola Kosta), the territory is more commonly divided into ten administrative regions for local mancomunidades, regional planning, and tourism purposes.
