Indianapolis International Airport (IATA: IND, ICAO: KIND, FAA LID: IND) is a public airport located seven miles (11 km) southwest of the central business district of Indianapolis, a city in Marion County, Indiana, United States. The airport is the largest in Indiana and is a major hub for FedEx. It is also a focus city for AirTran Airways and Delta Airlines.

ATA's demise at IND gave Northwest Airlines an opportunity to greatly expand its operations at the airport. This service expansion allowed Indianapolis to become a focus city for that air carrier, which itself became a wholly owned but separately operated subsidiary of Delta Air Lines in late 2008.

A state-of-the-art 1.2 million square foot midfield terminal has been constructed. It has two concourses, A and B.
