Aubrey Levin (born December 18, 1938) is a South African-born Canadian psychiatrist and former Colonel in the South African Defence Force who used abusive procedures on homosexual army conscripts and conscientious objectors in an attempt to cure them of supposed vices in apartheid era South Africa.
During the 1970s and 1980s, Levin subjected many homosexual men to electroshock or chemical castration, and over 900 conscripts were forced to undergo involuntary sexual reassignment surgery.
In 1995 Levin moved to Canada and acquired a license to practice medicine.
He became professor of clinical psychiatry at the University of Calgary.
In 2010 he was arrested for sexual assault of a patient; thirty men claimed they were assaulted by Levin during counseling.
Levin was tried and convicted for assault, sentenced to five years in prison, and his medical license was suspended.
