Oneida County Airport (IATA: UCA, ICAO: KUCA, FAA LID: UCA) was a public airport in Whitestown in Oneida County, New York, six miles (9.7 km) northwest of downtown Utica.

Federal Aviation Administration records say the airport boarded 2,122 passengers in calendar year 2004 and 1,951 in 2005.

USAir had a presence at UCA until 1995 when it ended jet flights and closed its maintenance base and reservations center.

UCA had no airline service after Continental Connection carrier CommutAir left on June 30, 2002.

In its final years, UCA flights had been under the EAS program; declining ridership led the required subsidy to breach the $200 per passenger statutory cap.
