Members of the Marine Corps League join together in camaraderie and fellowship for the purpose of preserving the traditions and promoting the interested of the United States Marine Corps.  This is accomplished by banding together those who are now serving in the United States Marine Corps and those who have been honorably discharged from that service; voluntarily aiding and rendering assistance to all Marines and Veteran Marines and to their widows and orphans, and by perpetuating the history of the United States Marine Corps through fitting acts to observe the anniversaries of historical occasions of particular interest to Marines.

​​​The Marine Corps League is an organization for all Marines.... Active Duty, Reserve, Veteran, Retired, Officer, and Enlisted!  We also welcome Navy Corpsmen who have served with Marine units.

​​The Marine Corps League was founded by Major General Commandant, John A. Lejeune, in 1923 and chartered by an Act of Congress on August 4, 1937.  Its membership of 60,000 is comprised of honorably discharged, active duty and Reserve Marines with 90 days of service or more, and retired Marines.  It includes officer, enlisted, male and female members.
