His career started with his hometown team of Hartlepool United where he signed as a youngster in 1985. After a stay at Leicester City, he signed in 1987 for Wolverhampton Wanderers. Over nearly a decade at Molineux, Venus was an integral part of the club's resurrection after bankruptcy. Playing left back and, occasionally in his preferred position of central defence, Venus helped Wolves to Divisions Four and Three championships. He joined Ipswich Town in 1997 after being exchanged for Steve Sedgley. With Ipswich Town he won the 1999–2000 First Division play-offs, and then finished 5th in the Premier League, qualifying for the UEFA Cup. Ipswich were relegated in 2001–02, but Venus picked up the club's Player of the Year award. He was given a free transfer by Ipswich Town managerJoe Royle at the end of 2002–03. Whilst playing for Cambridge United in 2003–04, he fell out with the club and played the rest of that season on loan to Dagenham & Redbridge.
Coaching career
Venus was hired as Hibernian assistant manager by his former Ipswich Town teammate Tony Mowbray in 2004. Venus also registered as a player for Hibs, but played in only one match before ending his playing career. He returned to the West Midlands in October 2006 by following Mowbray to West Bromwich Albion. Their first game in charge was a Black Country derby against Wolves, where Venus had spent the bulk of his playing career. Venus was appointed Celtic assistant manager on 16 June 2009, again following Mowbray. After Mowbray was sacked as Celtic manager in March 2010, Venus and Peter Grant also left the club. Venus was appointed assistant manager of Middlesbrough on 26 October 2010, working again with Mowbray. After Mowbray was sacked by Middlesbrough in October 2013, Venus was made caretaker manager. Middlesbrough chairman Steve Gibson commented that Venus was on the shortlist of candidates to be the next permanent manager. On 25 October he led Middlesbrough to a 4-0 win over Doncaster Rovers. Mark Venus' tenure as caretaker manager came to an end on 13 November when Aitor Karanka was appointed as the new Middlesbrough head coach. Venus joined Coventry City in June 2015 as technical director. After the resignation of Tony Mowbray on 29 September 2016 he was made caretaker manager.
