The Battle of Harlem Heights was fought in the New York Campaign of the American Revolutionary War. The action took place in what is now the Morningside Heights and west Harlem neighborhoods of Manhattan in New York City on September 16, 1776.

The Americans—under Generals George Washington, Nathanael Greene, and Israel Putnam, totaling around 2,000 men—held a series of high ground positions in upper Manhattan against an attacking British division totaling around 5,000 men under the command of General Alexander Leslie. British troops made what became a tactical error by sounding a fox hunt bugle call while in pursuit, meant to insult the Continentals, who were in orderly retreat. This instead infuriated the Americans who galvanized to hold their ground. The battle went a long way to restore the confidence of the Continental Army.
