Brydan Klein (born 31 December 1989) is an Australian-born British former professional tennis player. As a junior, Klein won the 2007 Australian Open and reached a career-high top five in the ITF junior rankings. However, Klein has struggled to make the transition onto the men's professional circuit, failing to enter the top 150 or gain entry into any Grand Slam event without being given a Wild card.
Klein competed mainly on the ATP Challenger Tour.
