The town of Fishkill also contains a village named Fishkill. The town is in the southwest part of the county, partly surrounding the city of Beacon.
Fishkill played an important role in the Revolutionary War when a vast military encampment was established one mile (1.6 km) below the village to guard the mountain pass to the south. Signal fires lay in readiness on tops of the surrounding mountains. The Fishkill encampment became the main supply depot for the northern division of the Continental Army. The first 1,000 copies of the New York State Constitution were turned out on Samuel Loudon's press at Fishkill in 1777. Trinity Episcopal Church became a hospital for soldiers recovering from smallpox, and the Dutch Reformed Church was used as a military prison.
The town of Fishkill was created in 1788 as part of a general formation of towns in Dutchess County. Fishkill was reduced by the formation of the towns of LaGrange (1821} and East Fishkill (1849).
