The Illawarra Steelers are an Australian rugby league football club based in the city of Wollongong, New South Wales. The club competed in Australia's top-level Rugby League competition from 1982, when they, along with the Canberra Raiders, were admitted into the then New South Wales Rugby Football League premiership until 1998 when they formed a new joint venture team, the St. George Illawarra Dragons with the St. George Dragons in 1999. Over those seventeen seasons the club received three wooden spoons, made the play-offs twice and had a total of three of its players (two New South Wales Blues and one Queensland Maroon) selected to don the green and gold for Australia.
The Steelers still field stand alone teams in junior grades. Their mascot was the popular Stanley, the Steel Avenger (commonly referred to as Stanley the Steeler).
