Thamesmead F.C. was formed in 1969 as a community team for local youngsters. The club merged with Southlake FC in 1973, and by 1979 were fielding a Saturday team, playing on park pitches at Crossways. In 1980 the club entered the
London Spartan League at the Intermediate Division Three level. They dominated the intermediate divisions in the early 1980s, but were unable to gain promotion to the Senior Division until they gained senior status. At around this time, they played matches at the Meridian Sports Ground in Charlton. In 1985, the club changed its name to Thamesmead Town FC, and later that year they relocated to Bayliss Avenue. The club finally gained senior status during the summer of 1987 and were accepted into the London Spartan League Premier Division for the 1987–88 season. The club joined the Kent League in June 1990, where they remained until 2008, generally finishing amongst the top half dozen in the table. In 2002–03, they missed the runner-up spot on goal difference, despite having scored more points than league champions
Cray Wanderers. This was due to placings being decided on points per game after
Faversham Town failed to complete the season. In 2007–08, Thamesmead Town were champions of the Kent League, winning the title on the last day of the season. The title ensured promotion to the
Isthmian League, where they were elected to play in Division One North in 2008–09. In 2012–13, Thamesmead finished 3rd in this division. They beat
Witham Town 3–2 in the play-off semi-final and
Maldon & Tiptree on penalties in the final to gain promotion to the Isthmian League Premier Division for the first time in their history. The following season, however, Thamesmead were relegated back to Division One North. At the end of January 2015 manager Keith McMahon quit the club after 11 years at the helm. Due to the club owner's inability to find a new buyer, along with low match attendance and little income revenue, partly due to the lack of a home stadium after moving from Thamesmead to ground share with Dartford F.C. in 2017, the club announced its closure in October 2018. ==Stadium==
