Jacob Leisler (ca. 1640 – May 16, 1691) was a German-born colonist in the Province of New York. He gained wealth in New Amsterdam (later New York City) in the fur trade and tobacco business. In what became known as Leisler's Rebellion following the English Revolution of 1688, he took control of the city, and ultimately the entire province, from appointees of deposed King James, in the name of the Protestant accession of William and Mary.
