The Kūkō Line (空港線, Kūkō-sen; lit. 'Airport Line') is a subway line, part of the Fukuoka City Subway system in Fukuoka, Japan. It connects Meinohama, Nishi Ward to Fukuokakūkō (Fukuoka Airport), Hakata Ward, all within Fukuoka. The line's color on maps is orange. Officially, the line is called Line 1 (Kūkō Line) (1号線(空港線), Ichi-gō-sen (Kūkō-sen)). The line has a through service with the JR Chikuhi Line. Like other Fukuoka City Subway lines, stations are equipped with automatic platform gates, and trains are automatically operated by an ATO system. However, JR train cars (from Chikuhi Line) are operated manually.

This is the only subway line in the country that directly links to an airport. Although Toei Asakusa Line trains in Tokyo also serve airports (Narita and Haneda), those are not the stations of the Asakusa Line itself. Rather, they are the stations of suburban lines that the Asakusa Line has through services with.

The Kūkō Line goes through many important areas of the city, namely Nishijin, Tenjin, Hakata, and the airport.

All stations are in Fukuoka, Fukuoka Prefecture.
