Ramon Berenguer III the Great (11 November 1082 – 23 January or 19 July 1131) was the count of Barcelona, Girona, and Ausona from 1086 (jointly with Berenguer Ramon II and solely from 1097), Besalú from 1111, Cerdanya from 1117, and count of Provence in the Holy Roman Empire, from 1112, all until his death in Barcelona in 1131.

Ramon Berenguer also raided mainland Muslim dependencies with Pisa's help, such as Valencia, Lleida and Tortosa.

In 1116, Ramon traveled to Rome to petition Pope Paschal II for a crusade to liberate Tarragona.

[4] By 1118 he had captured and rebuilt Tarragona, which became the metropolitan seat of the church in Catalonia (before that, Catalans had depended ecclesiastically on the archbishopric of Narbonne).

[citation needed] In 1127, Ramon Berenguer signed a commercial treaty with the Genoese.
