Marco Island Executive Airport (IATA: MRK, ICAO: KMKY, FAA LID: MKY), also known as Marco Island Airport, is a public airport located in Naples, Collier County, Florida, four miles (6.4 km) northeast of the central business district of Marco Island. This airport is publicly owned by Collier County.

The Marco Island Executive Airport is conveniently located to Naples, Marco Island, Goodland and Isles of Capri.

The airport was initially designed to complement plans to create a resort area south of Naples. Immediately following completion in 1976, the airport was primarily used as a marketing tool to help sell Marco Island lots. Developers would fly prospective Marco Island homeowners and investors over from Miami. Eventually the developers turned the airport over to the state of Florida, and in the 1980s the state, in turn, leased it directly to the county. Recognizing that the airport represents a community asset, the county had the foresight to maintain the airport, and in 1993, the Collier County Airport Authority was created to develop and manage the Marco Island Executive Airport. Today, the airport represents a community asset, with travelers from all over the world making their way to this general aviation airport just north of Marco Island.

Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, Marco Island Airport is assigned MKY by the FAA and MRK by the IATA (which assigned MKY to Mackay Airport in Mackay, Queensland, Australia).
