Joel Reddy (born 8 October 1985) is an Australian former professional rugby league footballer who most recently played for the South Sydney Rabbitohs.

Reddy played for Parramatta in the club's 2007 reserve grade premiership winning side which defeated North Sydney 20–15 at Telstra Stadium.

Unveiled in The Daily Telegraph's exclusive fan poll on 23 September 2009, Reddy was chosen as the most under-rated player in the NRL.

Reddy played for Parramatta in the 2009 NRL grand final and scored a try in the second half but The Eels ultimately lost the match 23–16.

He signed with the South Sydney Rabbitohs for the 2014 season, the year in which they won the premiership but did not feature in the grand final winning side.
