Vagrant Story is a 2000 action role-playing video game developed and published by Square for the PlayStation. The game has been re-released by Square Enix through the PlayStation Network for the PlayStation 3, PlayStation Portable and PlayStation Vita consoles. Vagrant Story was primarily developed by the team responsible for Final Fantasy Tactics, with Yasumi Matsuno serving as director, producer, designer, and writer.

The game takes place in the kingdom of Valendia and the ruined city of Leá Monde. The story centers on Ashley Riot, an elite agent known as a Riskbreaker, who must travel to Leá Monde to investigate the link between a cult leader and a senior Valendian Parliament member, Duke Bardorba. In the prologue, Ashley is blamed for murdering the duke and the game discloses the events that happen one week before the murder.

Vagrant Story is unique as a console action role-playing game in that it features no shops and no player interaction with other characters; instead, the game focuses on weapon creation and modification, as well as elements of puzzle-solving and strategy. The game received critical acclaim from gaming publications, with some calling it one of the greatest games ever made.
