Which Paper Mario game was released on the Nintendo GameCube?

The Paper Mario game released on the Nintendo GameCube is Paper Mario: The Thousand-Year Door. Developed by Intelligent Systems and published by Nintendo, it launched in Japan in 2004 before reaching North America, Europe, and Australia later that year.

The game is the second main entry in the Paper Mario series, following the original Paper Mario on Nintendo 64. Mario travels through the paper-crafted world while searching for the seven Crystal Stars and uncovering the mystery of the Thousand-Year Door. Its turn-based battles, timed attacks, badges, partners, and theatrical audience became defining features.

A common mix-up is Super Paper Mario, which also features paper-themed characters but was released for the Wii in 2007. Paper Mario: Sticker Star appeared on Nintendo 3DS in 2012, while Paper Mario: Color Splash was a Wii U title. The Thousand-Year Door later received a Nintendo Switch remake in 2024.
