Ultima II: The Revenge of the Enchantress, released on August 24, 1982 for the Apple II (USCO# PA-317-502), is the second role-playing video game in the Ultima series, and the second installment in Ultima's "Age of Darkness" trilogy.

It was also the only official Ultima game published by Sierra On-Line. Controversy with Sierra over royalties for the PC port of this game led the series creator Richard Garriott to start his own company, Origin Systems.

The plot of Ultima II revolves around the evil enchantress Minax, taking over the world and exacting revenge on the player for the player's defeat of Mondain in Ultima. The player travels through time to acquire the means to defeat Minax and restore the world to peace. Ultima II has a larger game world than Ultima I, and hosts advances in graphics and in gameplay.
