Orange City Municipal Airport (ICAO: KORC, FAA LID: ORC) was a city-owned public-use airport located one nautical mile (1.85 km) south of the central business district of Orange City, a city in Sioux County, Iowa, United States.

[2] Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this facility was assigned ORC by the FAA but had no designation from the IATA[3] (which assigned ORC to Orocue Airport in Orocue, Colombia[4]).

Orange City Municipal Airport covered an area of 80 acres (32 ha) at an elevation of 1,414 feet (431 m) above mean sea level.

For the 12-month period ending August 19, 2009, the airport had 4,200 general aviation aircraft operations, an average of 81 per week: 43% local and 57% itinerant.
