Campbeltown Airport (Scottish Gaelic: Port-adhair Cheann Loch Chille Chiarain) (IATA: CAL, ICAO: EGEC) is located at Machrihanish, 3 nautical miles (5.6 km; 3.5 mi) west of Campbeltown, near the tip of the Kintyre peninsula in Argyll and Bute on the west coast of Scotland.

The airport was formerly known as RAF Machrihanish (after the village of Machrihanish) and hosted squadrons of the Royal Air Force and other NATO air forces as well as the United States Marine Corps. The airport is at a strategic point near the Irish Sea, and was used to guard the entrance to the Firth of Clyde where US nuclear submarines were based at Holy Loch and where Royal Navy Trident missile submarines are still based at HMNB Clyde (Faslane Naval Base).

The United States Navy handed the airfield back to the MoD on 30 June 1995, marking the end of its service as a NATO facility since 1960. The airbase was sold to Machrihanish Airbase Community Company (MACC) in May 2012, and two thirds of the runway is leased to Highlands and Islands Airports for Campbeltown Airport.

At 3,049 m (10,003 ft), the original runway 11/29 at Campbeltown Airport is the longest of any public airport in Scotland.
