Orange City Municipal Airport

Orange City Municipal Airport 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. This airport was included in the FAA's National Plan of Integrated Airport Systems for 2009–2013, which categorized it as a general aviation facility.

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 (which assigned ORC to Orocue Airport in Orocue, Colombia ).

In 2018 the airport was closed and replaced by the new Sioux County Regional Airport located 5 miles to the west.
