The 2013 Cronulla-Sutherland Sharks season is the 47th in the club's history. Coached by Shane Flanagan and captained by Paul Gallen, they competed in the NRL's 2013 Telstra Premiership. The Sharks finished the regular season 5th (out of 16), thus reaching the finals for a second consecutive season. They were then knocked out of contention in the second week of the finals by eventual grand finalists the Manly-Warringah Sea Eagles. This year Damian Keogh became chairman of the club's board of directors.
