Gaston II Centule (circa 951 – 1012) was the Viscount of Béarn from 996 to his death. He succeeded his father Centule III after the latter's assassination at the hands of Lupus the Strong, Lord of Serres.

Gaston granted the village of Asson to the abbey of Lescar, whose abbot was then García Lupus, his brother. Gaston was succeeded by his then minor son Centule IV under the regency of his mother.
