About MCA

The Marine Corps Association is the professional organization of the United States Marine Corps, founded more than 100 years ago by General John A. Lejeune. MCA is a member based organization dedicated to professional development, recognition of excellence, and building awareness of the rich traditions, history and esprit of the United States Marine Corps. Our non-profit arm, the Marine Corps Association Foundation, supports Marines through four programs which provide unit libraries, commanders’ forum events and professional military education trips to Marines throughout the world.
