Sackboy is a fictional character and main protagonist of the LittleBigPlanet video game series published by Sony Interactive Entertainment. Introduced in the 2008 video game LittleBigPlanet, Sackboy is a small, anthropomorphic, humanoid doll-like character made of burlap sack with a brown knit pattern by default, with a zip fastener and button eyes. Sackboy was originally designed to be a "blank canvas" for LittleBigPlanet players, and is fully customisable using costumes which are either in-game unlockable content, or purchased as downloadable content (DLC) from the PlayStation Store. Sackboy was jointly created by the founding members of British game studio Media Molecule. Scottish composer Kenneth Young provided the vocal effects for the character from 2008 to 2014.
Due to the commercial and critical success of the LittleBigPlanet franchise, Sackboy is considered to be a notable mascot character for Sony's PlayStation brand by Sony staff members as well as video game journalists, and has drawn comparisons to several other video game mascot characters. The character's appearance in the 2020 spin-off title Sackboy: A Big Adventure, the first 3D platforming game in the series which also features Sackboy as a distinct character, has garnered a positive reaction.
