The 1979 New York Cosmos season was the ninth season for the New York Cosmos in the now-defunct North American Soccer League.

1979 saw the club continue their premiership streak to three seasons with the league's highest point total, and match their wins record while achieving a record point total, but the Cosmos' quest for a third straight NASL championship ended with a loss in the conference finals to the Vancouver Whitecaps.
