About United States Marine Corps Birthday

The United States Marine Corps Birthday is observed on November 10, marking the date in 1775 when the Second Continental Congress authorized two battalions of Marines.

Modern formal commemoration dates to 1921, when Commandant John A. Lejeune issued Marine Corps Order No. 47 directing that a birthday message be read to commands on November 10 each year.

Why United States Marine Corps Birthday matters

The birthday is an institutional tradition of the Marine Corps, connecting serving Marines, veterans and units with the Corps’ history and customs.

It is not a general U.S. civilian public holiday. Birthday balls, cake-cutting ceremonies and command observances are Marine Corps traditions rather than nationwide closure rules.

History of United States Marine Corps Birthday

The Continental Congress resolved on November 10, 1775 that two battalions of Marines be raised.

Before 1921, the Corps birthday had often been associated with July 11, the 1798 date on which President John Adams approved legislation recreating the Corps.

On October 21, 1921, Maj. Edwin McClellan proposed returning the birthday to November 10. Commandant John A. Lejeune issued Marine Corps Order No. 47 on November 1, 1921 and directed annual reading of the birthday message on November 10.

Current Commandant birthday messages continue the annual institutional tradition.
