Rensselaerville (/ˈrɛnslərvɪl/) is a town in Albany County, New York, United States. The population was 1,826 at the 2020 census. The town is named after Stephen Van Rensselaer.

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. This path was also the one used during wars between the Stockbridge Indians and those at Schoharie.

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.

Rensselaerville was created from part of the town of Watervliet in 1790. In 1795, the northern part of the town was lost to create the new town of Berne. Additional territory was lost from the eastern part of the town upon the formation of the town of Westerlo in 1815.

In 1795, after Shays' Rebellion, Daniel Shays moved from Massachusetts to Preston Hollow, a hamlet in Rensselaerville. His son became one of the leading citizens of the town.

The Conkling–Boardman–Eldridge Farm and Rensselaerville Historic District are listed on the National Register of Historic Places.

According to the United States Census Bureau, the town has a total area of 61.9 square miles (160 km), of which 61.5 square miles (159 km) is land and 0.4 square miles (1.0 km) (0.63%) is water.

The southern town line is the border of Greene County, and the western town boundary is the border of Schoharie County. The town is located in the northern Catskill Mountains.
