Corpus Christi Roman Catholic High School (formerly Lady Mary, Welsh: Ysgol Uwchradd Corpus Christi) is a voluntary aided secondary school located in Pontprennau, Cardiff, Wales for years 7-11 (age 11-16). The school does not have a sixth form so pupils go to St. David's Catholic College for further education and for some vocational courses at GCSE. It is a Roman Catholic school but non Catholic students attend as well.
