Islington St Mary's Football Club was a football club based in north London, England.
Originally founded in 1978 as a youth team, the club won a number of local cups in the late 1980s and early 1990s.[2] In 1993, under the name of Walthamstow St Mary's, following a merger with Walthamstow Trojans in 1991, the club joined the Spartan League Division Two. In 1995, following promotion to Division One, the club changed name to Islington St Mary's.[2] [3] In 1996, Islington St Mary's won promotion to the Spartan League Premier Division. In 1997–98, the club was placed into the Spartan South Midlands League Premier Division South, following a merger between the Spartan League and the South Midlands League. The club's final season in senior football came in the 1998–99 season, entering the FA Vase for the first time.[4]
Upon the dissolving of the club, the club played at Coles Park in Tottenham.[2]
