LittleBigPlanet is a series of puzzle platform video games created by British developer Media Molecule and published by Sony Computer Entertainment on multiple PlayStation platforms.

Most games in the series place a strong emphasis on user-generated content and are based on the series' tagline "Play, Create, Share". The tagline represents the three core elements of the series: playing alone or with others locally (on the same console) or online, creating new content using the in-game creation tools, and sharing creations and discoveries online with other players.
