Joe Williams (born 4 September 1983) is an Australian sportsman who played rugby league and boxed as a professional.

His rugby league football career spanned from 2004 to 2008 and included appearances as a halfback and five-eighth with the Canterbury-Bankstown Bulldogs, Penrith Panthers and the South Sydney Rabbitohs in the NRL.

He made his debut for South Sydney in round 12 of the 2004 NRL season against Cronulla-Sutherland which ended in a 38–18 loss at Shark Park.

The following two seasons at Souths proved to be difficult as Williams was part of the side which finished last in 2006 and narrowly avoided the wooden spoon in 2005.
