John Sitton (born 21 October 1959), Hackney, London, England is a former professional footballer, manager of Leyton Orient Football Club and black cab driver. His playing career began at Chelsea F.C. and included spells at Millwall F.C., Gillingham F.C and Leyton Orient. Sitton co-managed Leyton Orient throughout the difficult 1994-1995 season with Chris Turner. Sitton is perhaps most well known for his passionate language and sacking one of his players at half-time during a match in which the Orient were 3-0 down. Since leaving Brisbane Road in 1995, Sitton managed Leyton F.C., Enfield F.C. and Leyton F.C. again. Alongside his career in transport, Sitton also works for the FA Coaching Education Scheme and compiles statistics for the Opta Index.
John Sitton is one of the few football managers to feature in a Channel 4 documentary, Orient: Club for a Fiver (made in 1995 by Open Media). To date this remains his only film credit.
Sitton again hit the headlines in 2006 with a bring John Sitton back into management petition campaign. As of September 2008, the petition had gained 241 signatures
