Cape Cod Gateway Airport (IATA: HYA, ICAO: KHYA, FAA LID: HYA), also known as Boardman/Polando Field and formerly known as Barnstable Municipal Airport, is a public airport located on Cape Cod, one mile (1.6 km) north of the central business district of Hyannis, in Barnstable County, Massachusetts, United States. This airport is publicly owned by Town of Barnstable. It is Cape Cod's major airport as well as an air hub for the Cape and the Islands (Martha's Vineyard and Nantucket). The airport is served by scheduled commercial flights as well as charters and general aviation. Barnstable Municipal Airport served as a hub for Nantucket-based commuter airline Island Airlines until its shutdown in 2015.

The airport was founded in 1928. During World War II it was also known as Naval Auxiliary Air Facility Hyannis, and both the Navy and Army Air Forces flew antisubmarine patrols from the airport.

It was renamed Barnstable Municipal Airport–Boardman/Polando Field in honor of Massachusetts aviation pioneers Russell Boardman and John Polando in 1981, the first aviators in history to fly non-stop for a 5,000-mile (8,000 km) distance.

As of January 1, 2021, the airport has rebranded itself as the Cape Cod Gateway Airport to provide better name recognition to users from off-Cape not familiar with the name Barnstable.
