Marine Corps Birthday (USMC Day)

The United States Marine Corps Birthday, celebrated each year on November 10, commemorates the founding of the Corps by the Second Continental Congress on November 10, 1775.

History of the Marine Corps Birthday

On November 10, 1775, the Continental Congress resolved to raise two battalions of Marines, marking the establishment of the original Continental Marines. After the Revolutionary War the force was disbanded, and later re-established officially on July 11, 1798.
In 1921, the Marine Corps formalised November 10 as its annual birthday celebration via Marine Corps Order No. 47, issued by Commandant John A. Lejeune, stating that “it is fitting that we who are Marines should commemorate the birthday of our Corps.”

Why is the Marine Corps Birthday important?

This day honors the long heritage, traditions and service of the Marine Corps—acknowledging the many thousands of Marines who have served from its founding to the present day. It reinforces the values of loyalty, courage and sacrifice that the Corps upholds.
It also connects current Marines with their predecessors: the formal birthday celebration helps preserve institutional memory, boost morale, and pass on the traditions that distinguish the Marines.

• It honours the founding date of the Marine Corps on November 10, 1775.
• It recognises the generations of Marines who have served in conflict and peace.
• It strengthens unit cohesion and pride in Corps identity.
• It sustains customs—such as the cake-cutting ceremony—that symbolise continuity and tradition.
• It encourages public appreciation of the Marine Corps’ role and heritage.

How to Celebrate or Observe the Marine Corps Birthday

Since this is a formal military institutional anniversary, it is appropriate to observe the day—with respect, recognition, and reflection—rather than a casual celebration. On this day, Marines around the world participate in traditional ceremonies, including balls, parades, and the cake-cutting event.
For civilians and supporters, celebrating might include thanking Marines or veterans, attending public events, or partaking in awareness activities.

• Attend or support a Marine Corps Birthday Ball or public commemorative event.
• Read or share the official Marine Corps Birthday Order (Marine Corps Order No. 47).
• Thank a Marine or veteran for their service and acknowledge Corps traditions.
• Learn about Marine Corps history and share stories of Marine heritage with others.
• Use social media to recognise the day and highlight Marine values, perhaps with the hashtag #MarineCorpsBirthday.
