Tomb Raider: The Last Revelation is an action-adventure video game developed by Core Design and published by Eidos Interactive. It was first released for PlayStation and Microsoft Windows in 1999, then on Dreamcast and Mac OS the following year. It is the fourth instalment in the Tomb Raider series. The narrative follows archaeologist-adventurer Lara Croft as she races to imprison the Egyptian god Set after accidentally setting him free. Gameplay features Lara navigating levels split into multiple areas and room complexes, fighting enemies and solving puzzles to progress.

Production of The Last Revelation began in 1998. Due to the strain of developing Tomb Raider titles non-stop since 1996, and general fatigue with the character, the Core Design staff wrote the narrative to end with Lara's death. While the same basic engine was used, it was extensively redesigned for better graphics and more intelligent enemy behaviour. The Dreamcast version emerged following the end of Sony's PlayStation exclusivity agreement with Eidos. The music was composed by Peter Connelly in his first major work on the series.

Reception of the game was generally positive, with many praising it as a return to form, but noting a lack of major innovation. Several critics felt the series was becoming stale. The Dreamcast port was generally criticised for its poor technical performance compared to other platforms. As of 2009, The Last Revelation was the fourth best-selling Tomb Raider title with over five million copies sold worldwide. Eidos insisted the series continue, and two more Tomb Raider titles began production at the same time; Tomb Raider: Chronicles for the same platforms as The Last Revelation, and The Angel of Darkness for the next console generation. A remastered version of the game was included in Tomb Raider IV–VI Remastered, released in 2025.
