Overlord II is a 2009 action role-playing game and sequel to the 2007 video game Overlord, developed by Triumph Studios and published by Codemasters for GNU-Linux , Microsoft Windows, Xbox 360, and PlayStation 3. All versions were released in North America on June 23, 2009, then later in Europe on June 26 and Australia on July 9, 2009, alongside two spin-offs; Overlord: Dark Legend and Overlord: Minions for the Wii and the Nintendo DS respectively. A Linux version was released on July 26, 2016.

Continuing the style of the series, the game is set in a fantasy realm where players take the role of the Overlord, a mysterious warrior whose goal is to destroy or conquer the land by commanding hordes of small creatures known as "Minions". The story directly follows the events of the first Overlord game, with the succeeding Overlord rising to power opposing a Roman-styled military power known as the "Glorious Empire". The story was written by Rhianna Pratchett and maintains a satirical tone and dark humor towards the fantasy setting and genre.
