Ramon Berenguer III was Count of Barcelona, Girona and Osona from 1097-1131.

He was the son of Ramon Berenguer II, and became count when his uncle Berenguer Ramon II was forced into exile.

During his rule Catalan interests were extended to the other side of the Pyrenees. He inherited the counties of Besalú (1111) and Cerdanya (1117) and in-between married Doulce, heiress of Provence (1112).

In 1114 joined with Pisa and Genoa in a short-lived occupation of Majorca.

Toward the end of his life Ramon Berenguer became a Templar. He gave his 5 Catalonian counties to his eldest son Ramon Berenguer IV and Provence to the younger son Berenguer Ramon.
