If you walk into any bar near a military base in the middle of November, you’re going to see something specific. It isn't just a party. It's almost a religious experience for a certain group of people. If you’re asking when is US Marines birthday, the short answer is November 10th. But honestly, just knowing the date is like saying you know a car because you saw a picture of the tire. To the United States Marine Corps, this isn't just a date on a calendar; it’s the heartbeat of their entire identity.
Most organizations have a founding date. Usually, it's a boring line in a HR manual or a reason for a corporate retreat. Not here. Every year on November 10, whether they are in a muddy foxhole in a remote jungle or sitting in a high-rise in Manhattan, Marines stop what they are doing to celebrate.
The Tun Tavern Legend: Where it All Actually Began
Let’s go back to 1775. Imagine a cold, smoky room in Philadelphia. This wasn't a sterile government building. It was a place called Tun Tavern. The Continental Congress needed "two battalions of Marines" to help fight the British, and they needed them fast.
Robert Mullan was the tavern owner. He also became the first unofficial recruiter. Think about that for a second. The toughest fighting force in the world was basically birthed in a bar. It’s a detail that Marines take a lot of pride in, and it’s why the US Marines birthday feels more like a family reunion than a formal ceremony.
There’s some historical debate, of course. For a long time, the Marines actually celebrated on July 11th. Why? Because in 1798, President John Adams signed an act formally re-establishing the Corps after it had been disbanded following the Revolutionary War. For over a century, that was the date. It wasn’t until 1921 that Major General John A. Lejeune (pronounced luh-jern) issued Order No. 47, which officially moved the celebration back to the original 1775 date. He wanted to anchor the Corps to its deepest roots.
General Lejeune’s Order: The Words That Refuse to Die
If you attend a Marine Corps Birthday Ball, you’re going to hear a reading. It’s the same reading every year. It’s Lejeune’s Marine Corps Order No. 47.
"In every battle and skirmish since the birth of our Corps, Marines have acquitted themselves with the greatest distinction, winning new honors on each occasion until the term 'Marine' has come to signify all that is highest in military efficiency and soldierly virtue."
It sounds a bit formal, sure. But when you hear it read in a room full of people who have seen combat, the air changes. It gets heavy. Lejeune didn't just want a party; he wanted a reminder. He wanted every Marine, from the youngest Private to the oldest General, to remember that they are part of a continuous chain.

The order is basically a legal requirement for the celebration now. It’s the soul of the event. It reminds them that they aren't just employees of the Department of Defense. They are the "Soldiers of the Sea."
The Cake Cutting Ceremony: A Lesson in Aging
The most famous part of the US Marines birthday is the cake. But it’s not just about eating dessert. There is a very specific, rigid protocol involved that would make a wedding planner sweat.
The first slice of cake is cut with a Mameluke sword. This sword is a piece of history itself, tracing back to the battle of Derna in 1805. The first piece goes to the Guest of Honor. But the second and third pieces are where the real emotion is.
The oldest Marine present takes a bite and then hands the piece to the youngest Marine present.
It’s a hand-off. It symbolizes the passing of experience, tradition, and "the torch" from the old breed to the new breed. I’ve seen 90-year-old Iwo Jima veterans hand a slice of cake to a 18-year-old kid who hasn't even been to his first unit yet. You can’t fake that kind of connection. It’s a literal bridge across generations.
Why 1775 Matters More Than You Think
People often wonder why the Marines care so much about being "older" than the country itself. The Declaration of Independence was 1776. The Marines? 1775.
That one-year difference is a massive point of pride. It suggests that before there was even a United States, there were Marines ready to fight for the idea of it. It’s about being the "First to Fight."

When you look at when is US Marines birthday, you're looking at a date that predates the formal existence of the nation they protect.
The Ball: Tuxedos, Blood Stripes, and Very Loud Music
The Marine Corps Birthday Ball is the social event of the year for the military. It’s not just one ball, either. Every unit, from the Pentagon to small detachments at overseas embassies, holds their own.
The dress code is the Evening Dress or Blue Dress "A" uniform. These are the ones with the high collars and the red "blood stripes" down the trousers. The stripe commemorates the high casualties taken by Marine officers and NCOs at the Battle of Chapultepec in 1847.
The vibe of these balls is unique. It’s half high-society gala and half rowdy family gathering. There’s a lot of "Ooh-rah-ing." There’s usually a video message from the Commandant of the Marine Corps. And honestly? There is usually a fair amount of beer, a nod back to the Tun Tavern days.
It’s Not Just About the Date
If you’re a civilian trying to understand the US Marines birthday, don't just look at the calendar. Look at the people.
For many veterans, November 10th is a day of reflection. They call their old friends. They remember the ones who didn't make it to the next birthday. It’s a day where the "Once a Marine, Always a Marine" slogan actually feels real. You’ll see guys who have been out of the service for forty years wearing their old covers or putting a Marine Corps flag on their porch.
I remember talking to a Vietnam veteran who told me he celebrates the Marine Corps birthday more than his own. "I didn't choose when I was born," he told me. "But I chose to be a Marine. This birthday is the one I earned."

Logistics of the Celebration
If you’re planning on attending a ball or just want to acknowledge the day, here are some things to keep in mind:
- The Date is Fixed: It’s always November 10th. If that falls on a Tuesday, the ball might be on a Friday or Saturday near it, but the "birthday" stays put.
- Veterans Day Connection: It’s conveniently (or perhaps by design) the day before Veterans Day. This creates a 48-hour window of intense military pride across the country.
- The Message: Every year, the Commandant releases a birthday message. It’s usually a high-production video that highlights the Corps' recent achievements and honors its history. It’s worth a watch on YouTube even if you aren't a Marine.
- The "Happy Birthday" Greeting: If you see someone in a Marine uniform on November 10th, or even someone with a Marine bumper sticker, saying "Happy Birthday" is the standard greeting. It’s better than "Thank you for your service" on that specific day. It shows you actually know what's going on.
Misconceptions About the Date
A lot of people confuse the Army birthday (June 14th) or the Navy birthday (October 13th) with the Marines.
While the Marines technically fall under the Department of the Navy, they are fiercely independent. Don't tell a Marine their birthday is in October. They won't be mad, but they will definitely correct you.
The 1775 date is non-negotiable. Even though the Corps was tiny back then—basically just a few guys on ships who were sharpshooters in the rigging—that's the lineage they claim.
Actionable Steps for November 10th
Whether you are a family member, a veteran, or just a curious patriot, there are real ways to engage with the US Marines birthday.
- Watch the Commandant’s Video: Every year, the official USMC social media channels drop a 5-to-10-minute video. They are usually incredibly well-made and give you a glimpse into the current state of the Corps.
- Reach Out: If you have a friend who served, send them a text. Just "Happy Birthday, Devil Dog" is enough. It hits different than a Veterans Day message. It shows you know their specific culture.
- Visit a Memorial: If you’re near D.C., the Iwo Jima Memorial (Marine Corps War Memorial) is the place to be. It’s powerful any day, but on November 10th, it’s electric.
- Read the History: Pick up a book like First to Fight by Victor Krulak. It explains why the Marine Corps exists and why it has had to fight just as hard to stay a separate branch as it has fought in any war.
The Marine Corps birthday isn't just a historical footnote. It’s a living, breathing tradition that keeps a relatively small group of people bound together across decades and continents. November 10th is the day that the "few and the proud" remind themselves why they bother being so different from everyone else. It’s about the tavern, the sword, the cake, and the stubborn refusal to let the past fade away.
To get the most out of this upcoming November 10th, look beyond the uniforms. Look at the way the youngest Marine looks at the oldest. That's where the real story is. Check the official Marine Corps website as November approaches to see the latest Commandant's message and find local community events that might be open to the public. Don't be afraid to stop by a local VFW or American Legion post—they'll likely be having a toast, and the stories you'll hear are better than any history book.
