Peekskill, officially the City of Peekskill, is a city in the New York City metropolitan area, Westchester County, New York, in the United States. Peekskill is situated on a bay along the east side of the Hudson River, across from Jones Point. The population was 23,583 during the 2010 census.
In September 1609, Henry Hudson, captain of the Halve Maen, anchored along the reach of the Hudson at Peekskill. His firstmate noted in the ship's log that it was a "very pleasant place to build a town". After the establishment of the province of New Netherland, New Amsterdam resident Jan Peeck made the first recorded contact with the Lenape people of this area, then identified as "Sachoes". The mills of Peek's Creek provided gunpowder, leather, planks, and flour. Slaughterhouses were important for food supply. The river docks allowed transport of supply items and soldiers to the several other fort garrisons placed to prevent British naval passage between Albany and New York City.Peekskill's first legal incorporation of 1816 was reactivated in 1826 when Village elections took place. The Village was further incorporated within the Town of Cortlandt in 1849 and remained so until separating as a city in 1940.
