East Fishkill is a town on the southern border of Dutchess County, New York, United States. The population was 29,029 at the 2010 census. The town name is derived from its formation from Fishkill, NY.
Hudson Valley Research Park (formerly known as IBM East Fishkill) is located in the town, and housed 27 divisions and 4,700 regular employees for IBM Microelectronics, that GlobalFoundries bought. While IBM produced microchips they owned the advanced, automated processor fabrication facility where IBM's "Cell" processor was co-developed.
One early settler arrived around 1759. The town of East Fishkill was established in 1849 from the eastern part of the town of Fishkill. The name "Fishkill" comes from that of the river which the Dutch settlers in the area called "Vis Kill" which means "fish creek".
