Mark Alexander Jackson (born 30 August 1959) is a former Australian rules footballer who played for the Melbourne Football Club, St Kilda Football Club and Geelong Football Club in the Victorian Football League (VFL), and for the South Fremantle Football Club in the West Australian Football League (WAFL). Known as "Jacko", Jackson's colourful and enigmatic personality often resulted in clashes with officials and teammates, which tended to overshadow the fact that he was also a capable full forward. Following his football career, Jackson became notable for several television appearances, including commercials for Jenny Craig, Energizer and Nutri-Grain, along with several feature films. Jackson has also written an autobiography, Dumb Like a Fox, which was released in 1986.

Melbourne (1981–1982) Jackson moved to Melbourne for the 1981 season, coached by Ron Barassi. Jackson performed a handstand in front of the Hawks full back, Kelvin Moore, reportedly after Moore had told him he "wouldn’t be a full forward while his arse pointed to the floor". Jackson on Open Mike said it was not pointed at Moore, rather it was directed at umpire Glenn James after he disputed a decision.
