The Marine Corps Association (often abbreviated MCA) is an independent association which provides a professional organization for members of the United States Marine Corps. It is known for its publications Leatherneck Magazine and Marine Corps Gazette. The MCA occupies a similar role with respect to the Marine Corps that the United States Naval Institute does for the United States Navy, the Association of the United States Army does for the United States Army, and the Air Force Association does for the United States Air Force.
