The Keisei AE series (京成AE形) was a DC electric multiple unit (EMU) train type operated by the private railway operator Keisei Electric Railway on Skyliner limited express services to and from Narita International Airport in Japan.

[1] First delivered in 1972, the trains operated between 1973 and 1993, and were replaced by Keisei AE100 series EMUs.

Five six-car sets were delivered in March 1972, entering service from December 1973 on reserved-seat limited express services between Keisei Ueno in Tokyo and Keisei Narita before the opening of the nearby Narita Airport.

[1] The new Skyliner services started on 21 May 1978, serving the original Narita Airport Station (present-day Higashi-Narita Station), and a further two six-car AE series sets were delivered in time for the start of these services.

One car, AE61, is preserved at Sogo Depot in Shisui, Chiba Prefecture.
