Gerardus Willemse Beekman (c. August 1653 – October 10, 1723)[1] was a wealthy physician, land owner, and colonial governor of the Province of New York.

[2] He was christened August 17, 1653 at Corlaer's Hook Plantation, New York, the second son of Wilhelmus Hendricksen Beekman (1623–1707) and Catalina De Boogh.

[3] When Henry Sloughter came to America in 1691 as Deputy Governor to succeed Nicholson, Beekman was arrested along with Leisler and others.

One farm extended for two miles along the Raritan River and contained 1,800 acres, held jointly with Laford Paterson, also of Flatbush, that was purchased for £366.

[8] He was the grandfather of James Beekman (1732-1807) the owner of Mount Pleasant, a mansion on Manhattan that was requisitioned by the British Army during the Revolution.

The fireplace mantle of the mansion, which features the Beekman family coat of arms, can be seen at the New York Historical Society.
