Bishop Hedley High School is a Roman Catholic secondary school, established in 1967, and located in Penydarren, Merthyr Tydfil, South Wales. The vast majority of the pupils of the school stem from the Heads of the Valleys, serving parishes from Aberdare, Hirwaun, Merthyr Tydfil, Merthyr Vale, Gurnos, Dowlais, Ebbw Vale, Tredegar and Rhymney. The school serves a catchment area of economic disadvantage which is a result of the decline of heavy industry, especially mining and steelmaking in the South Wales Valleys and the surrounding areas.
