The Keikyu 1000 series (京急1000形) was a DC electric multiple unit (EMU) train type formerly operated by the private railway operator Keikyu on commuter services in the Tokyo area of Japan from 1959 until June 2010.

The trains were used on the Keikyu Main Line, Keikyu Airport Line, Keikyu Daishi Line, Keikyu Zushi Line, and Keikyu Kurihama Line. They were also used on Toei Asakusa Line inter-running services until 2008. The last train made its final run in service on the Daishi Line on 28 June 2010.^[1]

The 1000 series fleet consisted of two-, four-, six-, and eight-car sets.^[2] By 2010, only four- and six-car sets remained in service, formed as shown below.^[3]

The M1 and M1c cars each had one lozenge-type pantograph.^[3]

Four 800 series cars were built in 1958 as prototypes, based on the earlier 700 series design.^[2] The type was subsequently reclassified "1000 series", with a further 352 vehicles built from 1959 to 1978. The early batches had non-gangwayed driving cabs with 2 windscreen panes, similar to the 700 series, but later batches included a centre gangway door at the cab ends.^[2] Sets built from 1971 onwards had air-conditioning from new, whereas earlier sets were subsequently retrofitted with air-conditioning.^[2]

Withdrawals commenced in 1986 with the arrival of 1500 series trains.^[2] Beginning in 1995, when the line speed between Shinagawa and Yokohama was raised to 120 km/h (75 mph), the 1000 series fleet was relegated from limited express services as, in spite of the sets' 120 km/h design speed, they were limited to only 110 km/h (68 mph) in service. By September 2001, the fleet had been withdrawn from daytime express services, before being withdrawn from all express services, as well as Toei Asakusa Line through services, by November 2008.^[4]

In 2008, one four-car set and one six-car set were repainted in early liveries to mark the 110th anniversary of Keikyu.^[2]

A number of 1000 series cars were resold to the Takamatsu-Kotohira Electric Railroad ("Kotoden") in Shikoku, becoming the 1080 series and 1300 series. Other cars were also resold to the Hokuso Railway, becoming the Hokuso 7150 series.^[2]

The identities and histories of the 1000 cars sold to Kotoden are as shown below.^[2]

Two 1000 series cars, 1351 and 1356, remain stored at Keikyu's Kurihama Works.^[2]
