Dunsbach Ferry is a hamlet of the town of Colonie, in Albany County, New York, United States.

There are numerous private and public docks and landings between the Twin Bridges and the Colonie Town Park.

In 1718, an early settler and ferry owner, Cornelius Claes Vandenburgh, built a landmark stone house on the Mohawk west of Crescent.

Howell for measuring the discharge flow of the river and the record continued on at the West Troy Water Company dam and pumping station at the hamlet, it was located roughly 200 feet south (upstream) of the bridge.

Many of the homes along the river began as summer cottages and have been winterized and enlarged while some still remain in strictly summer-camp style.
