Hartwick is a town located in Otsego County, New York, United States.

He bought the area (the Hartwick Patent, granted 1761) that now constitutes the township from the Mohawk Indians in 1763.

Discontented with the sparsely settled communities of Palatine Germans in the Mohawk Valley to the north, which Hartwick believed made people immoral, he bought the original Hartwick Patent with the intent to build a "New Jerusalem".

The largest commercial enterprise to occur in Hartwick was probably the Southern New York Railroad which was constructed to the town in 1901.

It was supported by extensive shops, a car barn and yards on the southeast side of the village.

Many of the hamlets and crossings still show architectural signs related to the trolley line nearly a century after the last passenger service.
