The Keikyu 1500 series (京急1500形^?) is an electric multiple unit (EMU) train type operated by private railway operator Keikyu on commuter services in the Tokyo area of Japan since 1985.

The 8-car sets are primarily used on limited-stop "Rapid Limited Express" and "Limited Express" services on the Keikyu Main Line, including through-running services to and from the Toei Asakusa Line subway, Keisei Main Line, and Hokuso Line. The 4- and 6-car sets are mostly used on all-stations "Local" services. The 1500 series sets can be used in multiple with other Keikyu EMU types, including the 600 series, N1000 series, 2000 series, and 2100 series.

As of 1 April 2012^[update], the fleet consists of 166 vehicles formed as 4-car, 6-car, and 8-car sets, as follows.

11 x 6-car sets formed by adding two 1900 trailer cars to 4-car sets.

6 x 8-car sets formed by adding two 1900 trailer cars to 6-car sets.

Passenger accommodation consists of longitudinal bench seating throughout.

The 1500 series fleet was built between 1985 and 1991. The first five 4-car sets delivered had steel bodies, while all subsequent sets had aluminium bodies with door pocket windows discontinued. Sets built from 1990 onward used VVVF control.

A programme of life-extension refurbishment commenced in 2002. This involved adding new air-conditioning units, removing the original door pocket windows of the steel bodied cars, and adding front-end skirts.
