The United States Marine Corps birthday is an American holiday celebrated every year on 10 November with a traditional ball and cake-cutting ceremony. On that day in 1775, the Continental Marines were established.

The official birthday of the United States Marine Corps is on 10 November 1775. That was the day when the Second Continental Congress established the Continental Marines with the following decree:

That two battalions of Marines be raised consisting of one Colonel, two lieutenant-colonels, two majors and other officers, as usual in other regiments; that they consist of an equal number of privates as with other battalions, that particular care be taken that no persons be appointed to offices, or enlisted into said battalions, but such as are good seamen, or so acquainted with maritime affairs as to be able to serve for and during the present war with Great Britain and the Colonies; unless dismissed by Congress; that they be distinguished by the names of the First and Second Battalions of Marines.
