Every year on November 10, Americans proudly say “Happy Birthday US Marines” to honor one of the most admired military branches in the world — the United States Marine Corps. In 2025, that message carries even greater meaning. This year marks the 250th anniversary of the Marine Corps, celebrating two and a half centuries of courage, loyalty, and dedication to the nation.
Across the United States and around the globe, Marines — active duty, veterans, and families — are preparing to mark this historic milestone. It’s more than a celebration; it’s a tribute to a legacy that has protected freedom since 1775.
The Beginning: Where the Marines Were Born
The story of the Marine Corps began on November 10, 1775, when the Second Continental Congress passed a resolution to create two battalions of Marines. The new force was designed to serve both at sea and on land, supporting naval operations during the American Revolution.
Recruitment began at Tun Tavern in Philadelphia, Pennsylvania, a place that would become legendary in Marine history. Captain Samuel Nicholas, a Philadelphia native, became the first Commandant of the Marine Corps and led the newly formed “Continental Marines.”
Those first Marines set the foundation for what would become a global symbol of discipline, strength, and sacrifice. From the nation’s earliest days, the Marine Corps earned a reputation as a force that could be counted on — first to fight, last to quit.
Why November 10 Matters So Much
When people say “Happy Birthday US Marines,” they are honoring the very day the Marine Corps came into existence — November 10, 1775. It’s a date that every Marine knows by heart.
The official tradition of celebrating the Marine Corps Birthday began in 1921, thanks to Major Edwin North McClellan, who recommended the Corps formally recognize its founding date each year. Since then, Marines have observed the day through ceremonies, speeches, and moments of reflection — no matter where they are in the world.
For Marines, the birthday isn’t just another event. It’s a time to reconnect with history, pay respect to those who served before them, and renew their commitment to the values that define them: honor, courage, and commitment.

Traditions That Define the Marine Corps Birthday
The Marine Corps Birthday is known for its powerful and meaningful traditions. Each one connects Marines across time and rank.
The Cake-Cutting Ceremony
The highlight of every celebration is the cake-cutting ceremony. The oldest Marine and youngest Marine in attendance cut the cake together, symbolizing the bond between generations. The oldest Marine then passes a slice to the youngest, representing the transfer of knowledge, honor, and duty.
General Lejeune’s Message
Another cherished tradition is the reading of General John A. Lejeune’s Birthday Message from 1921. His words remind Marines of their shared history, their role in defending freedom, and the responsibilities that come with wearing the uniform.
A Moment of Reflection
In every Marine unit, big or small, there’s a moment to remember those who gave their lives in service. Marines pause to honor their fallen brothers and sisters, ensuring their memory remains part of the Corps’ living story.
The Meaning of “Happy Birthday US Marines”
The words “Happy Birthday US Marines” carry deep emotion and pride. For Marines, this greeting is personal — a recognition of shared experience, sacrifice, and loyalty.
Every Marine, no matter their rank or era, belongs to the same family. Saying “Happy Birthday” connects those who fought decades apart — from the battles of Iwo Jima and Khe Sanh to operations in Iraq and Afghanistan.
It’s a reminder that once you earn the title Marine, it stays with you for life. You never stop being part of that brotherhood and sisterhood bound by Semper Fidelis.

These observances show that the Marine Corps is not just a military institution — it’s part of the American identity.
The Modern Marine Corps: Adapting for the Future
As the Marine Corps celebrates its 250th year, it continues to evolve to meet the challenges of a changing world. Modern Marines train not only for combat but also for humanitarian missions, disaster relief, and cybersecurity defense.
