Rennae Stubbs (born 26 March 1971 in Sydney) is an Australian tennis player. She was an Australian Institute of Sport scholarship holder. She has won several Grand Slam doubles titles and represented Australia at four successive Olympic Games; Atlanta 1996, Sydney 2000, Athens 2004 and Beijing 2008.
Stubbs has recorded more doubles triumphs than any other Australian woman—60 from 1992 to the conclusion of the 2010 WTA Tour—enjoying success with eleven different partners. She also won two mixed doubles Grand Slam titles with male partners. In 2001, Stubbs won the season-ending WTA Championships with regular partner Lisa Raymond and the pair were named ITF World Champions.
Stubbs is the longest-serving member of the Australia Fed Cup team, having played for 17 years since 1992, with a 28–9 win/loss record in doubles; the second highest in Australian Fed Cup Team history behind Wendy Turnbull (29–8). She retired after the 2011 Fed Cup tie with Italy. However, Stubbs suddenly came back to the WTA Tour by playing at the Miami Masters with Jill Craybas.
Stubbs is openly lesbian.
