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 services operating at up to 160 km/h using new Keisei AE series EMUs.

Narita International Airport Corporation owns a 63.74% majority stake in Shibayama Railway as of July 2009.

Trains utilize the Keisei Electric Railway's Main Line between Keisei Ueno and Keisei-Takasago. Trains run at a maximum speed of 160 km/h, thus completing the run from Nippori to Narita Airport Terminal 2·3 in a minimum of 36 minutes, 15 minutes faster than the previous Skyliner route, which took 51 minutes. The reserved-seat Keisei Skyliner fare for the route between Narita airport and either Nippori or Ueno stations is ¥2,400 and takes 36-41 min., but the Access Express commuter fast train costs ¥1,200 and takes about 78 min. Express trains also operate to Haneda Airport from Narita Airport via Keisei-Takasago and Aoto then via the Keisei Oshiage Line to Oshiage, and on the Toei Asakusa Line via Shimbashi to Sengakuji, the Keikyu Main Line and via Shinagawa to the Keikyu Airport Line. This makes it possible to connect the two airports in a minimum of around 65 minutes, compared to the previous minimum of 106 minutes. Many Express trains separate (or connect) at Aoto station and continue to the Keikyu Haneda International Airport station (¥1,630, about 76 min.) or one can transfer at Shinagawa (on the way to Haneda) to stay on the Keikyu Main Line for Yokohama (¥1,630, about 101 min.).
