The New South Wales Rugby League premiership was the first rugby league football club competition established in Australia and contributor to today's National Rugby League. Run by the New South Wales Rugby League (initially named the New South Wales Rugby Football League) from 1908 until 1994, the premiership was the state's elite rugby league competition, parallel to Queensland's first-class league, the Brisbane Rugby League.
For most of the premiership's history it was contested by clubs from the state of New South Wales only, but later attempted to grow into a nationwide competition, eventually leading to the competition being played under the auspices of the Australian Rugby League in 1995. Despite this name, the 1995 and 1996 Australian Rugby League Premierships competitions were still administered by the Board and staff of the New South Wales Rugby League.
