The 2003 NRL premiership was the 96th season of professional rugby league football in Australia and the sixth run by the National Rugby League. Fifteen teams competed, with the Manly-Warringah Sea Eagles returning in place of their failed joint-venture club, the Northern Eagles. Ultimately, the Penrith Panthers defeated reigning champions, the Sydney Roosters in the 2003 NRL grand final, claiming their first premiership since 1991.
