Major Celebrations & Events
Nationwide and Themed Events
To commemorate the 250th Marine Corps Birthday, the Marine Corps has launched a series of “Marine Weeks” across major U.S. cities, including Los Angeles, Nashville, Chicago, Boston, and Atlanta. Each event features live demonstrations, static displays, and interactions between Marines and local communities.
A major highlight of the celebrations took place in Philadelphia—the birthplace of the Marine Corps—during “Homecoming 250” week in October 2025. The event included a ship parade on the Delaware River, historical reenactments, and a special ceremony honoring Marines of all generations.
The grand culmination will occur on November 10, 2025, when Marines around the nation participate in official birthday ceremonies and traditional cake-cutting events at bases, embassies, and gatherings worldwide.
Leadership and Commemorative Activities
High-ranking Marine leaders, veterans, and government officials have participated in numerous 250th anniversary events. In Washington, D.C., a formal Marine Corps Ball highlighted the deep bond between the Corps and the American people.
The United States Mint has also launched a commemorative coin program to mark this milestone, featuring a gold $5 coin, a silver $1 coin, and a half-dollar clad coin. These limited-edition coins symbolize 250 years of honor, courage, and commitment.
Another initiative, “Marines Across America,” honors active-duty Marines and veterans in every U.S. state, alongside a 50-State Cake-Cutting campaign to unite Marines nationwide in celebration.
