Eareckson Air Station (IATA: SYA, ICAO: PASY), formerly Shemya Air Force Base, is a United States Air Force military airport located on the island of Shemya, in the Alaskan Aleutian Islands.

The airport was closed as an active Air Force Station on 1 July 1994. However, it is still owned by the USAF and is operated by the USAF Pacific Air Forces Regional Support Center at Elmendorf AFB for refueling purposes. It also serves as a diversion airport for civilian aircraft. The base previously hosted the AN/FPS-17 and AN/FPS-80 radars and since 1977 the more powerful AN/FPS-108 COBRA DANE phased-array radar.
