Cyber Speedway (Gran Chaser in Japan) is a 1995 racing video game developed by Nextech and published by Sega for the Sega Saturn.

The game was originally called Grand Racer, but was renamed to avoid confusion with another early Saturn game, Gale Racer. It is a spiritual sequel to the 1993 computer game CyberRace; the two games share a similar theme, and vehicles designed by Syd Mead.
