Established in 1986, the Private Schools Athletic Association (PSAA) is a sports league for independent high schools primarily located in the New York Metropolitan Area.

Prior to the 1920s, New York City had the longest history with private schools leagues, beginning with the New York Interscholastic Athletic Association formed in 1879.

During World War I, the private schools felt the need of a league, and got together for a track and field meet in the spring of 1917.

New York’s Catholic schools during much of the 1920s did not have much league sponsorship, and also participated in league events, notably DelaSalle, Bishop Loughlin, St. Augustine (defunct), and La Salle Military Academy (defunct); they now participate in the Catholic High School Athletic Association (CHSAA).

The following independent school sport leagues are also in New York state:
