St John's Gardens in central Manchester, England, lies between Lower Byrom Street, and Quay Street. Previously occupied by St John's Church and its graveyard between 1769 and 1931, the site was redeveloped into a formal garden in 1932. It contains a central memorial to the church and those buried in its graveyard, whose tombstones have been covered over by 18 inches (460 mm) of soil except for that of John Owens, founder of Owen's College. The garden was awarded a Green Flag in 2012 and is part of the St John Street conservation area.
