Trevor Daley (born October 9, 1983 in Toronto, Ontario) is a Canadian professional ice hockey defenseman with the Dallas Stars of the National Hockey League.

Daley was drafted by the Dallas Stars in the 2002 NHL Entry Draft, 43rd overall, in the second round from the Sault Ste. Marie Greyhounds of the Ontario Hockey League.

In his final year with the Greyhounds and as captain, Daley found himself the victim of a racial slur by then Coach and General Manager, former NHL goaltender John Vanbiesbrouck. Daley quit the team and upon the resignation of Vanbiesbrouck returned to the team three days later to finish out the 2002–03 season.
