The Monastery of Sant Benet de Bages is a former Benedictine monastery, in the comarca of Bages, Catalonia, Spain. The Romanesque monastery was thoroughly restored at the beginning of the twentieth century by the Catalan architect Josep Puig i Cadafalch.

The monastery was founded about 950 by the noble Salla and his consort Ricarda, of the house of the viscounts of Osona. According to the founding legend, Salla traveled to Rome to have his institution authorized, and to have it depend directly on the Holy See, the usual method for preserving the community from interference from the bishop— in this case of Vic— in whose diocese it lay. The abbey church was consecrated 3 December 972, witnessed by a gathering of notables: Borrell II, Count of Barcelona, the bishops Frugifer of Vic, Guisad of Urgell and Pere of Barcelona, the viscount Guadald of Osona, and three of the four offspring of the recently deceased founder, his son Isarn and the sisters Quíxol and Ego, at the head of witnesses both laymen and priests, in a grand ceremonial recorded in the surviving act of consecration.

The community was dedicated to the Holy Trinity and to Benedict of Nursia (Sant Benét in Catalan), founder of the order, and Peter and Andrew, all guarantors of its future orthodoxy. The founder secured dispensations that the future abbots would be chosen from among their descendents, making the abbey a form of proprietary church, an agreement that would soon lead to disputes among the various branches of their lineage as to choice of abbots.
