The Circuito Lasarte was an Grand Prix motor racing road course at Lasarte-Oria, Guipúzcoa, Spain in the Basque Country near the city of San Sebastián on the Bay of Biscay. The counterclockwise layout was used between 1923 and 1935 but racing ended with the eruption of the Spanish Civil War in 1936 and after the war auto racing resumed at new tracks near Barcelona. The Circuito Lasarte played host to the San Sebastian Grand Prix, Spanish Grand Prix and the 1926 European Grand Prix. No longer operational for auto racing, in 1965 the layout was used for the World Cycling Championship.
