Idaho County Airport (IATA: IDH, ICAO: KGIC, FAA LID: GIC, formerly S80) is a county-owned, public-use airport in the western United States. Located in north central Idaho, it is one nautical mile (1.15 mi, 1.85 km) north of the central business district of Grangeville, the seat of Idaho County.

Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned GIC by the FAA and IDH by the IATA (which assigned GIC to Boigu Island Airport in Queensland, Australia).
