Olympia Regional Airport[1][2][3] (IATA: OLM, ICAO: KOLM, FAA LID: OLM) is a public use airport located four nautical miles (7 km) south of the central business district of Olympia, a city in Thurston County and the capital of the U.S. state of Washington.

The airport's industrial park, 300 acres (1.2 km2) in extent, includes a U.S. Department of Commerce-designated free trade zone.

The airport now supports large business jets, cargo aircraft, military helicopters and has a backup runway lighting system for uninterrupted operations.

Olympia Regional Airport covers an area of 845 acres (342 ha) at an elevation of 208 feet (63 m) above mean sea level.

The field is home to fixed wing and helicopter flight instruction, major aircraft and oxygen maintenance facilities, the Washington State Patrol aviation division, and a key navigational aid (Olympia VOR) that is used by commercial flights inbound to Seattle-area airports, including Seattle-Tacoma International Airport, as well as by general aviation aircraft in the region.
