A Coast Guard Air Station (abbreviated as CGAS or AirSta) provides aviation support for the United States Coast Guard.

Fixed-wing aircraft, such as the HC-130 Hercules, are built for long range missions and operate from air stations.

The air stations and facilities are also home to locally based MH-65D Dolphin and Sikorsky HH-60 Jayhawk helicopters and support rotor craft assigned to flight deck equipped cutters.

Air stations are typically commanded by an officer with the rank of captain.

Air station planning and overall aviation policies are under the oversight of the Office of Aviation Forces (CG-711), which in turn reports to the Assistant Commandant for Capability.
