Centule IV Gaston (died 1058), called the Old, was the seventh Viscount of Béarn from 1012 to his death. He succeeded his father Gaston II while yet a minor, under a regency until 1022. He placed great importance on maintaining good relations with the church. In the year in which he assumed the powers of government, he founded the monastery of Saint-Pé-de-Geyres near the border with Bigorre. He was subsequently installed as the defensor of that monastery and of the lands of Saint Peter in Gascony and Béarn by his suzerain Sancho William, Duke of Gascony. In 1033, Centule confirmed the possession of the county of Bordeaux by Duke Odo.
