The 2015 Cronulla-Sutherland Sharks season is the 49th in the club's history. Coached by Shane Flanagan and captained by Paul Gallen, they competed in the NRL's 2015 Telstra Premiership. Starting the season as the previous season's wooden spooners, the Sharks finished the regular season in 6th place to reach the finals, winning their first play-off match but losing their second to eventual premiers North Queensland Cowboys and being knocked out of contention.
