F-Zero X is a futuristic racing video game for the Nintendo 64 (N64) console. Developed by Nintendo's EAD division, it was released in North America in 1998.

It was a sequel to the original 1990 F-Zero game, and is the first F-Zero installment to have featured 3D graphics. The game has a steep learning curve and its gameplay experience is similar to that of the original F-Zero game. F-Zero X introduced a "death race" mode and a random track generator called the "X Cup". In the death race, the player's objective is to annihilate the 29 other racers as speedily as possible, while the X-Cup "creates" a different set of tracks each time played.

Critics generally praised F-Zero X for its fast gameplay, abundance of courses and vehicles, track design, and maintaining a high framerate. However, the game has been widely criticized for its lack of graphical detail.
