Ely City was established in 1885 by members of Ely St. Etheldreda Football and Cricket Club and are the oldest senior football club in Cambridgeshire.

They won the Cambridgeshire Invitation Cup in 1969–70 and the Eastern CountiesLeague Cup in 1979–80, beating Lowestoft Town 4–2 on aggregate.

They returned to the Premier Division after winning Division One in 1996–97 and were Premier Division runners-up the following season, but were relegated again at the end of the 1998–99 season, which had seen them finish bottom of the Premier Division. Ely made an immediate return to the Premier Division as Division One runners-up in 1999–2000, also winning the Division One Cup. In 2002 they won the Cambridgeshire Invitation Cup, beating Histon 1–0 at the Abbey Stadium in Cambridge.
