Fat Princess is a downloadable video game for the PlayStation Network made by Titan Studios and sold by Sony Computer Entertainment. It was released in North America, Europe, and Brazil on July 30, 2009, and in Japan on December 25, 2009.

Fat Princess is primarily a zero to thirty-two multiplayer game with the basic goal of rescuing the Princess and bringing her back to the teams base. The players pick up and carry cakes to feed the Princess which makes her heavier and therefore harder for the enemy to carry back to their own castle. The game contains six character classes (The Villager, The Worker, The Priest, The Ranger, The Mage, and The Warrior) each of which helps contribute to the teams task of capturing the princess in a unique way. As of June 16 2010 at E3, Sony announced three new classes to be available through the Fat Roles DLC Expansion Pack. The three new classes include Pirates, Ninjas and Giants.
