Manor of Rensselaerswyck

The Manor of Rensselaerswyck, Manor Rensselaerswyck, Van Rensselaer Manor, or just simply Rensselaerswyck , was the name of a colonial estate—specifically, a Dutch patroonship and later an English manor—owned by the van Rensselaer family that was located in what is now mainly the Capital District of New York in the United States.

The estate was originally deeded by the Dutch West India Company in 1630 to Kiliaen van Rensselaer, a Dutch merchant and one of the company's original directors. Rensselaerswyck extended for miles on each side of the Hudson River near present-day Albany. It included most of what are now the present New York counties of Albany and Rensselaer, as well as parts of Columbia and Greene counties.
