St Swithin, London Stone, was an Anglican Church in the City of London. It stood on the north side of Cannon Street, between Salters' Hall Court and St Swithin's Lane, which runs north from Cannon Street to King William Street and takes its name from the church. Of medieval origin, it was destroyed by the Great Fire of London, and rebuilt to the designs of Sir Christopher Wren. It was badly damaged by bombing during the Second World War, and the remains demolished in 1962.
