The National Music League (NML) was an American arts organization based in New York City that was active during the 1920s through the 1960s. Founded as a non-profit institution in June 1925, the organization was dedicated to supporting and furthering the careers of talented young American classical musicians. While its goals remained the same, the organization became a for-profit incorporated institution in 1938. Robert E. Simon served as the organizations president for many years and Léon Barzin served as vice president. The organization ceased operations in the early 1960s.
