Rushden & Diamonds Football Club was an association football club based in Irthlingborough, Northamptonshire, England. The club was formed by a merger of Southern Football League side Rushden Town and United Counties league side Irthlingborough Diamonds in 1992. Rushden & Diamonds played in the Conference National following a short spell in the Football League at the start of the 2000s. The club were expelled from the Conference National on 11 June 2011. Their unstable financial position meant they could not guarantee to complete all their fixtures in the then upcoming 2011–12 season, and resulted in their dissolution in 2011.
