Hancock Field Air National Guard Base is a United States Air Force base, co-located with Syracuse Hancock International Airport. It is located 4.6 miles (7.4 km) north-northeast of Syracuse, New York, at 6001 East Molloy Road, Mattydale, NY 13211. The installation consists of approximately 350 acres (1.4 km2) of flight line, aircraft ramp and support facilities on the south side of the airport.

Hancock Field is the home station of the New York Air National Guard's 174th Attack Wing (174 ATW), and the 274th Air Support Operations Squadron (274 ASOS). Both units are operationally gained by Air Combat Command (ACC).

The base employs approximately 2,000 personnel consisting of full-time Active Guard and Reserve (AGR), Air Reserve Technicians (ART) and traditional part-time Air National Guardsmen. ANG personnel maintains the BAK-14 arresting gear on the airport's primary runway for emergency use by military tactical jet aircraft. They also operates an Air Force crash fire station that augments the airport's civilian Aircraft Rescue and Fire Fighting (ARFF) department.

On 11 August 2008, it was reported that the 174th Fighter Wing would replace all F-16 Fighting Falcon fighter aircraft with MQ-9 Reaper unmanned combat aircraft. On 6 March 2010, the last 2 F-16Cs departed Hancock Field marking the end of F-16 aircraft operations at the base. Aircraft 85-1570 and 85-1561 made three low passes for the assembled crowd gathered to commemorate the end of manned aviation for the Wing. The unit then transitioned to the remotely piloted MQ-9 Reaper, and was re-designated as an Attack Wing with the new aircraft.
