Mark Porter is a former Australian rules footballer who played with Carlton and the Kangaroos in the Australian Football League. Originally from northern Victoria, Porter began his senior career as a teenager in the Ovens & King Football League, playing originally for Wangaratta, then King Valley. In 1994, at the age of just seventeen, and while playing for King Valley as a ruckman, Porter won the Baker Medal as the league's senior best and fairest. In 1995, Porter moved to Melbourne, and was recruited to the VFA by the Coburg Football Club. In his first season with the Lions, he won the Fothergill-Round Medal as the league's most promising young talent. Porter played two seasons for Coburg. After the 1996 season, Porter was recruited to the AFL as a rookie by the Carlton Football Club, which was looking for another ruckman with the emerging retirement of Justin Madden. Porter was the first player Carlton had recruited under the newly establishedrookie list. He made his AFL debut late in the 1997 season after Madden's mid-year retirement, and got regular games in 1998 as the second ruckman to Matthew Allan. Porter suffered a knee injury in a practice match prior to the 1999 AFL season, which saw him miss the entire season. He returned to the team in late 2000 and took part in their finals campaign. In 2001 he was a regular selection as Carlton's first choice ruckman, due to an injury to Allan, and he performed admirably, finishing seventh in the league for hit-outs with 381. After 2001, Carlton sought to improve its forward-line, and Porter was traded to the Kangaroos along with first and second rounddraft picks, in exchange for key forward Corey McKernan and second and third round draft picks. Porter played all but two games in 2002, alternating with Matthew Burton in the ruck and added another 19 games in 2003. Porter was delisted by the Kangaroos at the end of the 2004 season. In 2005, Porter played with North Ballarat in the VFL. In 2006 he moved back to northern Victoria, and played for Benalla in the Goulburn Valley Football League., playing there until 2007, before retiring.
