The Keisei Narita Airport Line (京成成田空港線, Keisei-Narita-Kūkō-sen) is a Japanese railway line connecting Keisei-Takasago Station and Narita Airport Terminal 1 Station. The entire route from Keisei Ueno Station, including the Keisei Main Line as far as Keisei-Takasago, is branded Narita Sky Access (成田スカイアクセス, Narita-sukai-akusesu).
The Keisei Electric Railway operates over the entire line, while other companies operate over certain sections of it, such as Hokuso Railway. The new line is used by Skyliner limited express services operating at up to 160 km/h (100 mph) using Keisei AE series EMUs.
