F1 Circus MD (エフワン サーカス エムディ?) is a multiplatform video game that was released for the Sega Mega Drive in addition to the PC Engine version of the game - which was released under the title F1 Circus '91 (エフワンサーカス'91?). This game uses the vehicles and the basic regulations of the Formula One circuit. The "Circus" part of the title is actually a mistranslation of the word Circuit. While loosely based on the 1991 Formula One season, the game uses drivers and racing teams with similar names to the officially licensed counterparts of that era. Team Lotus is considered to be the official co-sponsor of this video game along with its publisher Nichibutsu.
