F-Zero GX is a 2003 racing video game developed by Amusement Vision and published by Nintendo for the GameCube console. It runs on an enhanced version of the engine used in Super Monkey Ball.

F-Zero GX is the successor to F-Zero X and continues the series' difficult, high-speed racing style, retaining the basic gameplay and control system from the Nintendo 64 game. A heavy emphasis is placed on track memorization and reflexes. GX introduces a "story mode" element, where the player assumes the role of F-Zero pilot Captain Falcon through nine chapters while completing various missions.

The F-Zero GX and AX project was the first significant video game collaboration between Nintendo and Sega. GX was well received by critics for its visuals, intense action, high sense of speed, and track design. Complaints centered on its sharp increase in difficulty that may alienate players.
