The Eggnog Riot at the United States Military Academy concludes after beginning the previous evening.

The eggnog riot, sometimes known as the grog mutiny or the Christmas 1826 cadet mutiny, was a riot that took place at the United States Military Academy in West Point, New York, on 24–25 December 1826. It was caused by a drunken Christmas party in the north barracks of the academy. Two days prior to the incident, a large quantity of whiskey was smuggled into the academy to make eggnog for the party, giving the riot its name.

The United States Military Academy (USMA), commonly known as West Point, is a United States service academy in West Point, New York, that educates cadets for service as commissioned officers in the United States Army. The academy was founded in 1802, and it is the oldest of the five American service academies. The Army has occupied the site since establishing a fort there in 1780 during the American Revolutionary War, as it sits on strategic high ground overlooking the Hudson River 50 miles (80 km) north of New York City.
