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.

This community was known to be an early American industrial center, primarily for its iron plow and stove products. The Binney & Smith Company, now makers of Crayola products, started as the Peekskill Chemical Company at Annsville in 1864. Peekskill's manufacturing base operated well into the late 20th century, with the Fleischmann Company making yeast by-products under the Standard Brands corporate name.

The well-publicized "Peekskill" Riots of 1949 involved attacks and a lynching-in-effigy occasioned by Paul Robeson's benefit concerts for the Civil Rights Congress, although the main assault following the September concert properly occurred in nearby Van Cortlandtville.

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 date is not certain, (possibly early 1640s), but agreements and merchant transactions took place, formalized in the Ryck's Patent Deed of 1684. The name Peekskill derives from a combination of Mr. Peek's surname and the Dutch word for stream, kil or kill.
