Members of the Marine Corps League join together in  camaraderie and fellowship for the purpose of preserving the traditions and promoting the interests of the United States Marine Corps.

We band together those Marines and Navy Corpsmen who are now serving in and with the United States Marine Corps and those who have been honorably discharged that they may effectively promote the ideals of American freedom and democracy, voluntarily aiding and rendering assistance to all Marines and former   Marines and to their widows and orphans.

The MCL perpetuates the history of the United States Marine Corps by fitting acts to observe the anniversaries of historical occasions of particular interest to Marines.
