Hao Airport (IATA: HOI, ICAO: NTTO) is an airport on Hao Island in French Polynesia. The airport is 8 kilometres (5.0 mi) from the village of Otepa. Its unusually long runway (for the atoll's present population) was constructed to permit large transport aircraft (carrying materials for nuclear tests) to land. Their cargoes would be transported onward to nuclear test sites by ships.

Hao airport was a designated emergency landing site for the NASA Space Shuttle.
