The 1999 NRL season was the 92nd season of professional rugby league football in Australia, and the second to be run by the National Rugby League. With the exclusion of the Adelaide Rams and Gold Coast Chargers, and the joint venture of the St. George Dragons and Illawarra Steelers, seventeen teams competed for the NRL Premiership during the 1999 season, which culminated in the first grand final to be played at Stadium Australia. The St. George Illawarra Dragons, the first joint-venture club to appear in the grand final, played against the Melbourne Storm, who won the premiership in only their second season.
