Legend of Grimrock is an action role-playing game video game developed and published by Almost Human. The title is a 3D grid-based, real-time dungeon crawler based on the 1987 game Dungeon Master. It was originally released for Microsoft Windows in April 2012, and later ported for OS X and Linux in December 2012 and iOS in May 2015.

Legend of Grimrock was the debut game of Almost Human, a four-man Finnish indie development team formed in February 2011, which self-financed the title's development. A sequel, Legend of Grimrock II, was released in October 2014.
