The 2007 Cronulla-Sutherland Sharks season was the 41st in the club's history.
They competed in the National Rugby League's 2007 Telstra Premiership and finished 11th (out of 16).
The Sharks signed former Brisbane Broncos bad boy Brett Seymour who was sacked by that club last year.
2007 was a season of near misses for the largely inexperienced Sharks side with a large number of games lost by 4 points or less.
Notable wins included a first round shutout of the 2003 premiers Penrith 18–0 (indeed, Penrith went on to win the wooden spoon), a round nine win over the struggling premiers Brisbane at home which pitted NSW hopeful Greg Bird against Queensland captain Darren Lockyer, a golden point win over the Parramatta Eels at Parramatta, the venue of their infamous 74–4 loss just four years earlier and finally a 22–12 win over the Canberra Raiders in Canberra.
