The 287 series (287系, 287-kei) is a DC electric multiple unit (EMU) train type operated by West Japan Railway Company (JR-West) in Japan on limited express services such as the Kinosaki and Kounotori from Kyoto and Osaka since 12 March 2011. 287 series EMUs were introduced on Kuroshio services from the start of the revised timetable on 17 March 2012.

A total of 97 vehicles were built. These consist of 46 vehicles for Kinosaki, Kounotori, Maizuru, and Hashidate services, formed as seven 4-car sets and six 3-car sets, which will partially replace the ageing fleet of 86 183 series vehicles currently used on these services. A further batch of 51 vehicles for Kuroshio services consists of six 6-car sets and five 3-car sets, replacing older 381 series EMUs. These entered service from the start of the revised timetable on 17 March 2012.
