The Sega VR is an unreleased virtual reality headset prototype add-on for the Sega Genesis announced and worked on primarily by Sega of America throughout 1991-1994. Its release was ultimately cancelled due to development issues and younger users inducing motion sickness and severe headaches from use.

Only 5 games were known to have been announced or in development before its cancellation:
•Nuclear Rush: A simulation in which users pilot a hovercraft in a futuristic war.
•Iron Hammer: A shoot 'em up piloting a helicopter gunship inspired by EA's Strike series.
•Matrix Runner: Reportedly a cyberpunk adventure game inspired by Konami's Snatcher.
•Outlaw Racing: A vehicle racing and combat game.
•Virtua Racing: A port of Sega's 1992 Formula One racing arcade game announced as a launch title for the Sega VR. It's unknown how far this port made it into development, but Virtua Racing would later be released for the standalone Sega Genesis in 1994.

In November 2020, the Video Game History Foundation announced that they had successfully emulated the Sega VR's original hardware through HTC Vive with the help of fellow preservation website Gaming Alexandria by using parts of the source code of Nuclear Rush, as well as insight on the hardware and inner-workings of the cancelled games from some of their lead programmers.
