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.
