The 1937 New South Wales Rugby Football League premiership was the 30th season of the Sydney, New South Wales-based top-grade rugby league club competition, Australia's first.

Nine teams from across the city contested the premiership during the season, which lasted from April until June, with Eastern Suburbs being crowned champions.

[1] The 1937 season only lasted eight rounds due to the Kangaroo tour, and used a “first past the post” system to determine the premiers.

The second half of what would normally have been the NSWRFL season was taken up with a City Cup competition.
