Rensselaerville (/ˈrɛnslərvɪl/)[4] is a town in Albany County, New York, United States.

[6] Rensselaerville was once part of the Manor of Rensselaerswyck; as such, the people who farmed the land were technically leaseholders of the patroon under a feudal system, first as part of the Dutch colony of New Netherland, then under the English colony, and then U.S. state, of New York.

Some of the earliest settlement in Rensselaerville was along the five Native American paths that crossed the town in the early 18th century.

The southwestern corner along one of these, that connected the Hudson River to the Schoharie Valley, was the first section of the town to be settled, this would be circa 1712.

[6] In 1787, the patroon had a survey and census taken in order to enroll squatters and collect the quitrent required of settlers on his lands.

25.2% of all households were made up of individuals, and 10.7% had someone living alone who was 65 years of age or older.
