Indianapolis Regional Airport (ICAO: KMQJ, FAA LID: MQJ) is a public use airport in Hancock County, Indiana, United States. Owned by Indianapolis Airport Authority, it is 12 nautical miles (22 km) east of the central business district of Indianapolis. The airport is also 7 nautical miles (13 km) northwest of Greenfield and 3 nautical miles (6 km) southwest of McCordsville. It was known as Mount Comfort Airport until March 2011.

This facility is included in the National Plan of Integrated Airport Systems for 2017–2021, which categorized it as a general aviation reliever airport for Indianapolis International Airport. Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, Indianapolis Regional Airport is assigned MQJ by the FAA but has no designation from the IATA (which assigned MQJ to Moma Airport in Khonuu, Russia).
