Ian Harlow Stewart (né Cervi; born 14 July 1943) is a former Australian rules footballer who represented St Kilda and Richmond in the Victorian Football League (VFL) during the 1960s and 1970s.
He later coached South Melbourne and Carlton and was an administrator at St Kilda.
Stewart is one of only four men to win the Brownlow Medal three times.
He was one of the first inductees into the Australian Football Hall of Fame in 1996 and was elevated to Legend status the following year.
He will always be remembered as one of the truly great exponents of Australian football, a player with the rare blend of skill, concentration and courage who formed partnerships with two of the greatest forwards the game has produced, Darrel Baldock and Royce Hart.
Coincidentally, all three men hailed from Tasmania during a period when the country's smallest state contributed some unforgettable talent to the national game.
