Julian Knowle (born 29 April 1974) is an Austrian former professional tennis player. Being a born left-hander, Knowle was one of the few on the ATP Tour who played his forehand, backhand, and even volleys double-handed. He was Austria's most successful doubles player in history by reaching world No. 6 in the ATP doubles rankings in January 2008, before being matched by Jürgen Melzer, who reached No. 6 in September 2010, and overtaken only by Alexander Peya, who reached No. 3 in August 2013.
