The Ambush of Geary was a skirmish of the American Revolutionary War fought on 14 December 1776 near Ringoes in Amwell Township, Hunterdon County, New Jersey. Cornet Francis Geary, the leader of a company of dragoons, was shot in an ambush set up by local militiamen. Making a casualty of Geary was one of a number of militia actions that resulted in a reduced scope of British reconnaissance, contributing to the eventual success of George Washington's crossing of the Delaware and success at Trenton.
