The Class EH800 (EH800形^?) is a Bo'Bo'+Bo'Bo' wheel arrangement multi-voltage AC two-unit electric locomotive type operated by Japan Freight Railway Company (JR Freight) in Japan hauling freight trains on the Kaikyō Line through the Seikan Tunnel separating mainland Honshu with the northern island of Hokkaido. A prototype locomotive was delivered in January 2013 for evaluation and testing, with full-production locomotives delivered from June 2014, entering service from July 2014.

In order to allow Hokkaido Shinkansen services to operate through the dual-gauge Seikan Tunnel (which commenced on 26 March 2016), the overhead line system voltage was raised from the narrow gauge standard of 20 kV AC to the standard shinkansen power supply of 25 kV AC. A fleet of approximately 20 new dual-voltage locomotives capable of operating under either 20 kV or 25 kV was therefore required to replace the Class ED79 and Class EH500 locomotives previously used to haul freight and overnight sleeping car services through the tunnel. These locomotives are also compatible with the digital ATC and feature digital train wireless communications. The total cost of manufacturing the fleet of locomotives together with construction of new maintenance depot facilities was approximately 19 billion yen.

The Bo'Bo'+Bo'Bo' wheel arrangement locomotives are painted in an all-over red livery with a white bodyside line and silver wavy line.

The locomotives operate between Higashi-Aomori Freight Terminal and Goryōkaku Freight Terminal via the Kaikyō Line and Seikan Tunnel.
