Quillayute Airport (IATA: UIL, ICAO: KUIL, FAA LID: UIL), formerly known as Quillayute State Airport, is a public airport located approximately 10 miles (16 km) west of the city of Forks, in Clallam County, Washington, United States. It is owned by the City of Forks. This former Naval Auxiliary Air Station was deeded to the City of Forks by the Washington State Department of Transportation in 1999.

## Facilities and aircraft

Quillayute Airport covers an area of 739 acres (299 ha). For the 12-month period ending December 31, 2022, the airport had 6,700 aircraft operations: 97% general aviation and 3% military.
The airport has two concrete runways, each one close to 5,000 feet (1,500 m) long. Runway 12/30 is closed (the north–south runway). Runway 4/22 is open with a displaced threshold of 1,089 feet (332 m). In the Master Planning effort currently underway, it is the intent, in the long-term plan, to remove the displacement on runway 4/22 in the future, and reopen runway 12/30 at a shortened length.
