Dong Hoi Airport (IATA: VDH, ICAO: VVDH) (Vietnamese: Cảng hàng không Đồng Hới or Sân bay Đồng Hới) is an airport located in Loc Ninh commune, 6 km north of Đồng Hới city, capital of Quảng Bình Province, in North Central Coast of Vietnam, about 500 km South-east of Hanoi by road. The facilities cover 173 ha, on a sandy area, by the coast of South China Sea. The runway approaches near the seashore and nearly parallel to the Highway 1A. The airport, like all civil airports in Vietnam, is owned and operated by Airports Corporation of Vietnam.[2]

The airstrip was built unpaved by French colonists in the 1930s to serve the First Indochina War and was later upgraded by North Vietnam as an airbase for the Vietnam War. On 30 August 2004, the reconstruction of the airport began and was scheduled to be completed in 2006[3] but not until May 2008 was it inaugurated. On May 18, 2008, the airport was officially put into operation with the first commercial flight from Hanoi's Noi Bai International Airport.[4][5]

As of March 2015, this is one of 4 commercial airports in North Central Coast, the others are Phu Bai International Airport in Huế, Vinh Airport in Nghệ An Province, and Tho Xuan Airport in Thanh Hóa Province.

The airport handled 500,000 passengers in 2017, to its full designed capacity.[1] The airport is estimated to handle 700,000 passengers in 2018.[6]

An expansion project is planned to start in the Q4 2018, with the extension of the runway to 3600 m (category runway 4E) along with one parallel taxiway, capable of serving large aircraft like A350, B787, with two separate international and domestic terminals, with a combined designed capacity of 10 million passengers per annum.[7]
