The Testament of Sherlock Holmes is an adventure video game in the Sherlock Holmes series developed by Frogwares and distributed by Focus Home Interactive. After being delayed from an original 2010 release, the game was released in September 2012.

The game was developed primarily for consoles, and features a new graphic engine and gameplay mechanics. It is based on the fictional detective Sherlock Holmes, the protagonist of 56 short stories and 4 novels by Arthur Conan Doyle. Like many other games in the series, the game itself presents an original story and plot that is not based on any of Doyle's works. The Testament of Sherlock Holmes is set in the London of 1898 between the events of Sherlock Holmes: Crimes & Punishments and Sherlock Holmes: The Devil's Daughter, with Holmes presented as the main suspect in a case in which he is unable to prove his innocence; thus he must play a dangerous game to uncover the truth.
