Lego Star Wars II: The Original Trilogy is a 2006 Lego-themed action-adventure game developed by Traveller's Tales and published by LucasArts and TT Games Publishing. It was released on 11 September 2006. Part of the Lego Star Wars series, it is based on the Star Wars science fiction media franchise and Lego Group's Lego Star Wars construction toy line. It follows the events of the Star Wars films A New Hope, The Empire Strikes Back and Return of the Jedi. The game allows players to assume the roles of over 50 Lego versions of characters from the film series; customized characters can also be created. Camera movement was improved from its predecessor Lego Star Wars: The Video Game and the concept of "vehicle levels" was explored more thoroughly. The game was revealed at American International Toy Fair. Promotions for the game were set up at chain stores across the United States.

Lucasfilm Games is an American video game licensor and a subsidiary of Lucasfilm. It was founded in May 1982 by George Lucas as a video game development group alongside his film company; as part of a larger 1990 reorganization of the Lucasfilm divisions, the video game development division was grouped and rebranded as part of LucasArts. LucasArts became known for its line of adventure games based on its SCUMM engine in the 1990s, including Maniac Mansion, the Monkey Island series, and several Indiana Jones titles. A number of influential game developers were alumni of LucasArts from this period, including Brian Moriarty, Tim Schafer, Ron Gilbert, and Dave Grossman. Later, as Lucasfilm regained control over its licensing over the Star Wars franchise, LucasArts produced numerous action-based Star Wars titles in the late 1990s and early 2000s, while dropping adventure game development due to waning interest in the genre.
