St John's Church, Ranmoor is a large parish church in Ranmoor, a suburb of the City of Sheffield, England. It is a Church of England church in the Diocese of Sheffield, and it is the second church to be built on this site. The original church, designed by E.M. Gibbs, was opened 24 April 1879. This building was almost entirely destroyed by fire on 2 January 1887; all that survived was the 200-foot-tall (61 m) tower and spire (the tallest church spire in Sheffield). A new church, designed by Flockton & Gibbs (the same Gibbs), was built that incorporated the old tower and spire.
