Mark James Bentley (born 7 January 1978) is an English former professional footballer who is now a first-team coach at Southend United.

He was offered a new one-year contract to stay at Southend, but opted to go for the security of a two-year deal at Gillingham, signing for them on 22 May 2006.

Bentley was runner up in the club's 2006–07 player of the year award behind Andrew Crofts and signed a two-year contract extension in September 2007.

Following Jamie Hand's departure to Luton Town in early September, Bentley was appointed club captain.

[7] Bentley received widespread attention in March 2015 when he put himself on as a substitute in a game: he both scored and saved a penalty kick, helping turn a 2–0 deficit into a 3–2 win.
