The 1966 NSW First Division season was the tenth season of soccer in New South Wales under the administration of the NSW Federation of Soccer Clubs since its breakaway from the NSW Soccer Football Association in January 1957. The league once again played 18 rounds in the home and away regular season, beginning in March and ending in August. APIA Leichhardt finished first on the ladder to become regular season premiers for the second time after winning their first in 1964.
The finals series was primarily held throughout September with a four-team playoff series. For the first time a round robin was held between the top four clubs, culminating with a grand final between the top two placed teams. Hakoah defeated APIA Leichhardt in the decider.
The pre-season Ampol Cup was won for a first time by APIA Leichhardt.

It was decided that First Division wooden spooners, Corinthian BESC, would play-off against the second and third placed teams from the Second Division to earn the final two spots in the 1967 NSW First Division season.
The three-team play-off was contested over two matches with Canterbury receiving bye straight to the final match.
