Attapeu International Airport (IATA: AOU, ICAO: VLAP) was an international airport that served Attapeu in Laos. It opened in May 2015 following two years of construction. Lao Airlines provided flights from Vientiane via Pakse three times a week; however, it stopped them in October 2016 because of low passenger demand. The airport was officially closed in 2017. Attapeu Province has a small population (140,000) and does not receive much tourism, which have been cited as factors in the airport's closure. In 2022, the airport was handed over to the Lao People's Liberation Air Force.
