Iowa City Municipal Airport (IATA: IOW, ICAO: KIOW, FAA LID: IOW), is two miles southwest of downtown Iowa City, in Johnson County, Iowa. It is the oldest civil airport west of the Mississippi River still in its original location.

The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021 categorized it as a regional general aviation facility.

The airport has no scheduled airline service; the closest airline airport is The Eastern Iowa Airport in Cedar Rapids, about 19 miles (31 km) northwest. In the 1920s Iowa City was on the original transcontinental air route, flown by Boeing Air Transport, a United predecessor. On March 1, 1959, United was replaced by Ozark, which pulled out of Iowa City in April 1970.
