The Gave d'Aspe (French pronunciation: [ɡav dasp]) is a torrential river flowing through the Aspe Valley, one of the three main valleys of the High-Béarn (Pyrénées-Atlantiques), in the southwest of France. It is 58.1 km (36.1 mi) long.

It is formed in the Aspe Cirque, below the Aspe peak, elevation 2,643 metres (8,671 ft), in Spain.

After joining the Gave d'Ossau, in Oloron-Sainte-Marie, it forms the Gave d'Oloron.
