Gavan Neil Levenson (born 18 December 1953) is a South African professional golfer.

He won the Belgian Open and finishing in 29th place on the Order of Merit in his rookie season.

He spent four largely unsuccessful years on the tour, only recording one top ten finish when he tied for 4th place at the 1982 Greater Hartford Open.

He returned to Europe in 1985, and although he consistently finished inside the top 100 on the Order of Merit, he did not win again on the European Tour until the 1991 Open de Baleares.

Since turning fifty, Levenson has played on the European Seniors Tour, where he has one victory, achieved in just his second tournament, the 2004 DGM Barbados Open.
