The National Flute Association (NFA) is the largest flute organization in the world, with roughly 5,000 members from more than 50 countries. It is an association in the United States with headquarters in Chicago, Illinois. Members include soloists, orchestral players, jazz and world music performers, teachers, adult amateurs, and students of all ages.

The organization was founded in 1972 by flutist Mark Thomas and incorporated in 1973 in the state of Indiana. In 1973, an ad-hoc committee was created to help plan a convention of flutists. The group became the members of the first Board of Directors. Past presidents, program chairs, and committee chairs have included principal flutists of American orchestras, soloists and chamber musicians, and professors at conservatories and universities. Notable members include Sir James Galway and Ian Anderson. Rebecca Johnson is President of the Board for 2022-2024, and Jennifer Grim is Vice-President.

The first administrative role was established in 1977 and the organization currently has four full-time staff members. Jennifer Clarke was named the Executive Director in January 2021.
