Dr Mark Edward Loane AM FRANZCO FRACS (born 11 July 1954) is an Australian ophthalmic surgeon and former rugby union player.

He completed medical school and trained as an ophthalmologist in Queensland, where he continues to practice in both the public and private health systems.

His sporting career has been described by Bret Harris as "the closest thing to a folk hero Queensland has seen", and was noted for his game-winning barging runs.

He was selected that year to make the 1975–76 Australia rugby union tour of Britain and Ireland led by John Hipwell.

Two years later when Wales visited Loane again captained Queensland against the visitors and played in two spiteful Test matches, both won.

The first Grand Final was drawn after extra time against traditional rivals, Brothers, and another match was scheduled for the following week to decide the victors.

[6] Howell asserts that Loane's career peaked in 1981 when at aged 27 he was selected under the captaincy of his state arch-rival Tony Shaw on the 1981–82 Australia rugby union tour of Britain and Ireland.

Shaw had retaliated recklessly to niggling from Scots player Bill Cuthbertson with a king-hit right in front of the referee.

[6] Later that year Loane's stellar career came to an end after he captained Queensland and then Australia in two Tests against the visiting Scottish national side.

[7] He proceeded to complete Fellowships in both corneal transplantation and external eye disease (Flinders Medical Centre, South Australia) and in glaucoma (University of California San Diego, US).

[8] Loane has been involved in a number of charitable organisations and works, including serving as chair for the RANZCO Eye Foundation and as a board member for Guide Dogs Queensland.
