Castell de Sant Guim de la Rabassa is a historic building in Sant Guim de la Rabassa, municipality of Sant Guim de Freixenet in Lleida's Segarra region. First documented in 1078 through a testament referencing castle ownership granted to Guillem de Mir and his sons, the structure displays Renaissance influences with molded jambs and frames on its north facade. The rectangular building with ground floor, first and second levels stands adjacent to the old Jesuit convent, integrated within the village's primitive nucleus and included in the Inventory of Architectural Heritage of Catalonia.
