This is a list of airports in North Korea. North Korea is a country in East Asia, which may have as many as 78 usable airfields, although the state's secrecy makes it difficult to ascertain their number and condition with certainty. The state carrier, Air Koryo, joined the International Air Transport Association (IATA) in the late 1990s, and North Korea has proclaimed a program to upgrade several airports to international standards. However, with the exception of Pyongyang Sunan International Airport and a few that receive irregular service by Air Koryo, commercial aviation in North Korea is practically non-existent and most airfields appear to be military use.
