Tomato Adventure is a role-playing video game developed by AlphaDream and published by Nintendo for the Game Boy Advance on January 25, 2002, in Japan.

Players control DeMille through the Ketchup Kingdom while talking to people, entering places and collecting items. The object of the game is to save DeMille's girlfriend, Patharan, and the Ketchup Kingdom from King Abira by going through every village to obtain the missing parts of a robot that can give anyone access into the Gimmick Palace, a tower-like structure with a tomato on it. Instead of wandering endlessly inside places or entering battles randomly, Tomato Adventure displays enemies moving around on the screen while entering battles by bumping DeMille into them.
