St John's Church is a Roman Catholic Church building in Standishgate, Wigan, Greater Manchester. It is within 200 feet of another Catholic church, St Mary's. Construction on both churches, was done in a spirit of competition, so they both were finished in the same year, 1819. The competition was because St John's Church was originally served by the Society of Jesus, whereas St Mary's was always served by priests from the diocese. However, the Jesuits gave the church to the Archdiocese of Liverpool in 1933. It is a Grade II* listed building and the sanctuary inside the church was designed by Joseph John Scoles.
