Clyde Rathbone (born 23 July 1981 in Durban, South Africa), nicknamed "Rattlebones", is an Australian retired rugby union player.

After considerable speculation in the rugby world over which country he would represent at Test level, he opted for the Wallabies, which resulted in Rathbone being heavily criticized in much of the South African press.

Rathbone made his Test debut in June 2004 against Scotland, and went on to score a hat trick of tries against England the following week.

When the Wallabies went on tour that November, he scored a pair of tries against Scotland at Murrayfield, but suffered a groin injury that kept him out of the year's final Test against England.

[citation needed] In 2008, after 15 months out of rugby due to knee surgery for a torn patellar tendon, Rathbone signed a Shute Shield contract with the east-Sydney-based team, Easts.
