John Mansfield School was located in the Dogsthorpe area of Peterborough, England. The school opened in 1957, when the estate had just been completed, and was originally an all-girls school for those who failed the 11+. In 1981, it became a mixed school opened to all student form year 7 to post 16. In 2007 the school was closed and merged with two other schools, Deacon's Secondary School and Hereward Community College. The new school was relocated and called the Thomas Deacon Academy of Peterborough.
