Ian McMullin (born 1 September 1964) is a former Australian rules footballer who played in the VFL/AFL.
McMullin, an ex-Old Melbournian footballer, was recruited by Collingwood in the 1980s.
As a half-forward he was a noted goal-kicker.
McMullin was drafted by Essendon in the 1990 Pre-Season Draft.
After a few years at the Bombers, Collingwood showed interest once again, drafting him in the 1992 Mid-Season Draft, but McMullin only played another year; McMullin was released by Collingwood in 1993, after playing one game.
