The Keisei 3700 series (京成3700形) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Keisei Electric Railway in the Tokyo area of Japan since 1991.
The 3700 series eight-car sets operate on the Keisei Main Line between Keisei Ueno and Narita Airport, including inter-running services over the Toei Asakusa Line and Keikyu Main Line to and from Haneda Airport. As of November 2014[update], the six-car sets are used solely on the Keisei Main Line.

The first 3700 series sets were introduced in 1991, replacing the original 3000 series trains. The first six-car sets were delivered in 2000. Sets from the 6th batch onward (set 3828 onward) had restyled front ends with the headlights located near the roof. Two eight-car sets (3808 and 3748) were leased to the Hokuso Railway becoming Hokuso 7300 series sets 7808 and 7818, supplementing the two 7300 series sets owned by the Hokuso Railway.
