The 717 series (717系) is a Japanese AC electric multiple unit (EMU) train type first introduced by Japanese National Railways (JNR) in March 1985 and later operated on local services by the East Japan Railway Company (JR East) and Kyushu Railway Company (JR Kyushu). The units were formed by converting former AC/DC dual-voltage 451 series, 453 series, 457 series, and 475 series EMUs.

7 x 2-car 20 kV AC 60 Hz sets were converted from former 475 series cars with new bodies from November 1986 at JNR's Kokura and Kagoshima factories for use in Kyushu. The body design of these sets was identical to the earlier 713 series, with two pairs of sliding doors on each side. Four sets (HK201 to HK204) were converted in fiscal 1986, and three more sets (HK205 to HK207) were converted in fiscal 1987. The latter batch differed in having no door pocket windows.
These sets were painted white with a blue bodyside stripe.
