Star Wars: Purge: The Hidden Blade is a forty page comic book published by Dark Horse Comics on April 7, 2010. It was written by W. Haden Blackman and is part of a serial of one-shot comics covering the adventures of Dark Lord of the Sith Darth Vader after the fall of the Galactic Republic and the Jedi. This issue was preceded by Star Wars: Purge and Star Wars: Purge: Seconds to Die.

On a remote world, Darth Vader chafes at the assignment given to him by the Emperor: guarding an Imperial manufacturing facility from the anti-Imperial natives. Vader feels the duty is beneath him—until he learns that a Jedi Master and his Padawan are in league with the natives!

Now the game is afoot, and Vader is on the trail of his favorite prey. No ambush, no local monstrous lizards, will deter him his pursuit. Woe be to the Jedi when Vader catches up with them! This issue follows events in Star Wars: Episode III Revenge of the Sith!
