Rebecca Kate Brown (born 8 May 1977 in Brisbane, Queensland) is a former Australian breaststroke swimmer. Brown gained national exposure in March 1994 when, at 16 years of age, she broke Anita Nall's 200-metre breaststroke world record by 0.59 seconds in Brisbane. In the aftermath of that swim, she was feted as Australia's newest teen swimming sensation. However, at the 1994 Commonwealth Games in Victoria, Canada she lost out to Samantha Riley in both the 100 and 200-metre breaststroke events.
