Bradley Mousley (born 3 January 1996) is an Australian tennis player. Mousley won the Australian Open boys' doubles title in both 2013 and 2014.
As a junior, Mousley reached a career-high ITF Junior combined ranking of world No. 14, achieved on 3 March 2014. Partnering compatriot Jay Andrijic, he won the 2013 Australian Open boys' doubles tournament at 17 years old. He successfully defended the title, winning the boys' doubles championship for the second consecutive year at the 2014 Australian Open, this time alongside partner Lucas Miedler of Austria.
In August 2014, Mousley received a one-year ban, backdated to 30 May 2014, after testing positive for ecstasy in March. Mousley had admitted he had taken the drug at a party in March, and was originally given a two-year ban, but since the drug was not taken with the intent to enhance his performance, the ban was dropped to 12 months.
At the 2017 Australian Open, Mousley and partner Alex Bolt were granted a wildcard entry into the men's doubles main draw. Unexpectedly, they won three consecutive matches to reach the quarterfinals of the Grand Slam tournament, before being defeated by Spanish duo Pablo Carreño Busta and Guillermo GarcÃÂa López in three sets.
While competing in M15 World Tennis Tour tournament in Hua Hin Thailand, he injured his knee badly enough to have to withdraw from his singles semi-final match earlier in the day, and struggled to move freely from the start of his doubles finals match. He and partner Ajeet Rai were well-beaten by the top-seeded Ratiwatana twins in 40 minutes.
Mousley has won 2 singles titles and 18 doubles titles on the ATP Challenger and ITF Futures Tours.
