The 1980 New South Wales Rugby Football League premiership was the 73rd season of Sydney's professional rugby league football competition, Australia's first. Twelve clubs, including six of 1908's foundation teams and another six from around Sydney competed for the J.J. Giltinan Shield and WD & HO Wills Cup during the season, which culminated in a grand final between the Canterbury-Bankstown and Eastern Suburbs clubs. NSWRFL clubs also competed in the 1980 Tooth Cup and players from NSWRFL clubs were selected to represent the New South Wales team.
