New York Evacuation Day, observed on November 25, commemorates the day in 1783 when British forces evacuated New York City, marking the end of British occupation during the American Revolutionary War. This event took place after the signing of the Treaty of Paris, which officially ended the war and recognized the United States' independence.

The British had occupied New York City since 1776, and their departure was a significant victory for the American forces, led by General George Washington. The evacuation was celebrated as a triumph, symbolizing the end of British rule in the colonies and the beginning of a new chapter in American history.

New York Evacuation Day was widely celebrated in the city with parades, speeches, and festivities for much of the 19th century, reflecting the city's pride in its role during the Revolution. While the celebration has diminished over time, it remains an important historical event, marking the moment when New York City was finally liberated and solidifying the United States' independence.
