La Source is a ballet made on New York City Ballet by its founding balletmaster (and co-founder) George Balanchine. The premiere took place on November 23, 1968, at the New York State Theater, Lincoln Center.

Balanchine's had previously made a pas de deux to music from Léo Delibes' Sylvia in 1950; he expanded this into a divertissement in 1965. The final version uses music from Delibes' ballets La source and Sylvia and choreography from the earlier pas de deux and divertissement.
