Anachronox (released July 2001) is a computer game produced by Tom Hall and the Ion Storm games studio. It is a 3-D, third person RPG game. Development took around three and a half years.

The player plays the part of Sylvester "Sly" Boots, a down-and-out detective in the slums (known as "The Bricks") of an alien world called "Anachronox". Anachronox sits inside a giant, hollow sphere called Sender One, which is the centre of the galaxy's network of space-lanes.

"Sly" travels throughout the galaxy, meeting many characters along the way, some of who can join the player's party. Just some of these characters are Pal-18, Sly's robotic buddy; "Grumpos" Matavastros, a wiley old professor; and Stiletto the leather-suited assasin.
