Super Princess Peach (スーパープリンセスピーチ, Sūpā Purinsesu Pīchi^?) is a platform video game published by Nintendo for the Nintendo DS handheld game console. It was released in Japan in October 2005, the United States in February 2006, Australia in March 2006, and Europe in May 2006.

It is the first game to feature Princess Peach as the main playable character. In the game, Bowser has kidnapped Mario, Luigi, and Toad instead of Peach and holds them prisoner at Vibe Island, but Toad escapes from Vibe Island to the Mushroom Kingdom. Peach must go through eight worlds at Vibe to rescue Mario and Luigi.

Super Princess Peach was praised for the role reversal in the plot, but criticized for the nature of how Peach attacked, the marketing campaign, and the simple gameplay. It sold over a million copies worldwide.

Vibe Island, a land adjacent to the Mushroom Kingdom, has been rumored to hold hidden powers. Bowser decides to build a summer villa there in hopes of harnessing the rumored power. His efforts are rewarded when one of his underlings finds the Vibe Scepter. He sends a Goomba and an army of Hammer Bros. to Princess Peach's castle to capture Mario. The Vibe Scepter changes the emotions of those around them & they may become calm, happy, angry or sad. While all of the Toad servants are affected by the scepter's power, the Hammer Bros. seize Mario, Luigi, and Toad. Shortly after the capture, Toad escapes to the Mushroom Kingdom. Princess Peach, and Toadsworth, come back to the castle to find Mario and Luigi gone. Toad runs up to Peach, and Toadsworth attempts to convince Peach to not go after Mario and Luigi, but relents and gives her Perry, a talking parasol that has magical powers.

Princess Peach Toadstool (ピーチ姫, Pīchi-hime^?) is a character in Nintendo's Mario franchise. Originally created by Shigeru Miyamoto, Peach is the Princess of the fictional Mushroom Kingdom, which is constantly under attack by Bowser, and often plays the damsel in distress role within the series and is the lead female. She is often portrayed as Mario's love interest and has appeared in all the Mario games to date; with the most notable being Super Princess Peach where she is the main protagonist.

Princess Peach's initial appearance was drawn by Shigeru Miyamoto. Miyamoto later asked Yōichi Kotabe to redraw Peach with his instructions. He had asked Kotabe to draw her eyes to be "a little cat-like" and that she should look "stubborn, but cute". With Kotabe's influence, Princess Peach changed considerably throughout her gaming system. Peach was not a playable character in New Super Mario Bros. Wii because it would require special programming on how the game handles her dress, however, she is the main protagonist in Super Princess Peach and is a playable player in most Mario spin-offs such as Mario Party, Mario Kart and also sports games.
