Friedman Memorial Airport (IATA: SUN, ICAO: KSUN, FAA LID: SUN) is a city-owned public-use airport in the northwest United States, located one nautical mile (2 km) southeast of the central business district of Hailey, the county seat of Blaine County, Idaho. The airport is operated by the Friedman Memorial Airport Authority under a joint powers agreement between the city of Hailey and Blaine County. It serves the resort communities of Sun Valley and Ketchum, and the surrounding areas in the Wood River Valley.

Friedman Memorial Airport, the gateway to Sun Valley, is built on land donated to the city of Hailey by Leon and Lucile Friedman in 1931 and named in memory of their father, Simon M. Friedman. Simon was a local merchant and rancher who arrived in Hailey in the 1880s and served as mayor from 1909 to 1913.
