Tenzing-Hillary Airport (Nepali: तेन्जिङ हिलारी विमानस्थल, IATA: LUA, ICAO: VNLK), also known as Lukla Airport, is a domestic airport and altiport in the town of Lukla, in Khumbu Pasanglhamu, Solukhumbu District, Koshi Province of Nepal. The airport has gained worldwide fame, both for its unusual location, but also because it was rated the most dangerous airport in the world for more than 20 years by a program titled Most Extreme Airports, broadcast on The History Channel in 2010.

The airport is popular because it is considered the starting point for treks towards Mount Everest Base Camp. There are daily flights between Ramechhap or Kathmandu and Lukla during daylight hours in good weather. Although the flying distances are short, rain often occurs in Lukla while the sun is shining in Ramechhap or Kathmandu. High winds, cloud cover, and changing visibility often mean flights can be delayed or the airport closed. The airport is contained within a chain-link fence and is patrolled by the Armed Police Force Nepal, Nepal Civil Police or Nepali Army around the clock for security.
