Oneida County is a county located in the state of New York, in the United States. As of the 2010 census, the population was 234,878. The county seat is Utica. The name is in honor of the Oneida, an Iroquoian tribe that had this territory at the time of European encounter and has a reservation in the region.
Oneida County is part of the Utica-Rome, NY Metropolitan Statistical Area.
When colonial counties were established by England in New York State in 1683, the territory of present Oneida County was included in a very large, mostly undeveloped Albany County. This was an enormous county, including the northern part of New York State as well as all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation of Cumberland County, and further on March 16, 1770 by the creation of Gloucester County, both containing territory now in Vermont.
On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name Albany County. One of the other sections, Tryon County, contained the western portion (and thus, since no western boundary was specified, theoretically still extended west to the Pacific). The eastern boundary of Tryon County was approximately five miles west of the present city of Schenectady, and the county included the western part of the Adirondack Mountains and the area west of the West Branch of the Delaware River. The area then designated as Tryon County included what are now 37 individual counties of New York State. The county was named for William Tryon, colonial governor of New York.
