Simon Larose (born June 28, 1978) is a former professional tennis player. He was Canada's top-ranked singles player for some months during 2003 and 2004. Larose retired from the tour shortly after being banned for two years for substance abuse. Although Larose did not make any official announcement, he was quoted in the press as saying that he retired from tennis after being levied a two-year ban in February 2005 by the ATP for testing positive for cocaine. At the time of his supposed cocaine use, he had been out of action with a back injury.
