Fuenterrabia (Basque: Hondarribia; Spanish: Fuenterrabía; French: Fontarrabie) is a town situated on the west shore of Bidasoa river's mouth, in Gipuzkoa, in Basque Country, Spain.

The border town is situated on a little promontory facing Hendaye (France) over the Txingudi bay. A service boat makes the trip between the two cities. The town holds an ancient old quarter with walls and a castle. In addition, Fuenterrabia features a beach across the Bidasoa from the touristy housing estate Sokoburu in Hendaye, alongside a mountain called Jaizkibel providing a hilly backdrop to the town. A road leads north-east from the beach area to the Cape Higuer, located in this municipality.

The town harbours the San Sebastian Airport, which serves domestic flights. The population as of 2005 is 15,700 inhabitants.
