Melchior Ndadaye International Airport (IATA: BJM, ICAO: HBBA) is an airport in Bujumbura, the former capital of Burundi. It is Burundi's only international airport and the only one with a paved runway.

The airport was opened in 1952. On 1 July 2019, the airport was renamed Melchior Ndadaye International Airport after the first democratically elected president of Burundi who was murdered in a coup d'état in October 1993, three months after being elected. This event sparked the decade-long Burundian Civil War.

The airport is in the extreme northwest of Bujumbura Mairie Province. It is bounded by Bujumbura Rural Province to the north and west, by the RN4 coastal highway running along the shore of Lake Tanganyika to the south, and by the Mutimbuzi River and the RN5 highway to the east. The Mpanda River, a tributary of the Ruzizi River, flows past the north end of the airport.

In October 2018 the Burundi Civil Aviation Authority began dredging the Mutimbuzi River to prevent it from flooding into the airport. Drains would also be installed to prevent flooding. Removal of alluvium and other waste from the river would begin downstream and continue up to the NR5 highway from Bujumbura to Rugombo. In May 2021 the Mpanda River threatened to break the dam that protects the infrastructure of the Melchior Ndadaye International Airport.
