The Cathedral Church of St. John the Evangelist, usually known as Salford Cathedral, is a Catholic cathedral on Chapel Street in Salford, Greater Manchester, England.

St. John's Church, Salford, was built between 1844 and 1848 to designs of Matthew Ellison Hadfield (1812–1885) of Weightman and Hadfield of Sheffield, by Benjamin Hollins of Manchester. Hadfield's design for St. John's, the first cruciform Catholic church to be built in England since the Reformation, was closely modelled on a number of noted medieval churches.
