The Keikyu 2100 series (京急2100形) is a DC electric multiple unit (EMU) train type operated by the private railway operator Keikyu in the Tokyo area of Japan since 1998. It replaced the earlier 2000 series on limited-stop Limited Express (快特, Kaitoku) services. A total of 10 8-car sets were built by Kawasaki Heavy Industries, and Tokyu Car, and the first sets entered service on 28 March 1998.

Electrical systems
Its original GTO-VVVF propulsion system was supplied by Siemens. The ability to produce a "fa-so-la-ti-do-re-mi-fa-so" scale when the propulsion starts up quickly became a signature to the 2100 series when it was introduced, earning the nickname as the "singing train" (歌う電車). Subsequently, similar propulsion was also installed on 56 cars of the N1000 series. The uniqueness of the propulsion system made its way into various music and popular culture, such as Super Bell"Z. Due to the unavailability of substitute parts for the train's GTO-VVVF propulsion system, the propulsion system on every train was replaced with a new IGBT-VVVF propulsion system (supplied by Toyo Denki) that does not have a solfège scale.
Formation
As of 1 April 2012, ten 8-car sets were in operation, formed as follows, with four motored (M) cars and four trailer (T) cars, and car 1 at the Misakiguchi end.
The two "Tp" cars are each fitted with two single-arm pantographs.
Interior
Passenger accommodation consists of transverse seating arranged 2+2 abreast, with seat backs that can be flipped over to face the direction of travel. The windows on the 2100 series are double-glazed, with curtains.
Refurbishment
Set 2101 was the first 2100 series set to undergo refurbishment, in 2013. Modifications include replacing the passenger windows at the ends of each car with opening windows, replacing the curtains on these windows with roller blinds, and replacing the original fluorescent tube lighting with LED lighting.
By March 2015, all of the original Siemens-powered GTO-VVVF traction motors were replaced with new IGBT-VVVF traction motors manufactured by Toyo Denki.
Livery variations
Trainset 2157 carried a "Keikyu Blue Sky Train" livery, and used on airport services from 11 June 2005. From March 2015, set 2133 received the "Keikyu Blue Sky Train" livery. From 21 February 2016, set 2133 operated in a modified version of its blue livery, adapted to resemble the livery of Taiwan Railways Administration trains, to mark the first anniversary of the signing of a friendship agreement between Keikyu and Taiwan Railways Administration.
