Mansfield High School was a secondary school for 11- to 16-year-olds, in Brierfield, Lancashire. The school closed in June 2006 as part of the UK Government's Building Schools for the Future project. Edge End High School in neighbouring Nelson also closed its doors at the same time; the enrolled students from these two schools were merged into one and the new Marsden Heights Community College is now the secondary school serving this area.
