is an action-adventure role-playing video game developed by Intelligent Systems and published by Nintendo for the Nintendo 3DS. It is the fourth installment in the Paper Mario series and part of the larger Mario franchise; it is the first game in the series released on a handheld console. In the game, the protagonist Mario and a new ally named Kersti travel across the Mushroom Kingdom to retrieve the six Royal Stickers scattered by Bowser. The game was released in November 2012 in North America and December 2012 overseas.

Reception on the sticker mechanics was mixed. Gameplay Sticker Star features a similar visual style to its predecessors. The player controls a paper cutout version of Mario in a 3D papercraft world, with landscapes ranging from snowy areas and forests to volcanoes represented as the Mushroom Kingdom.

Mario is accompanied by Kersti, a sticker fairy, who bestows upon Mario the power of stickers.
