Dark Ages: Inquisitor is a supplement published by White Wolf, Inc. in 2002 for the horror role-playing game Dark Ages: Vampire

In 1991, White Wolf created the horror role-playing game Vampire: The Masquerade set in the modern-day World of Darkness universe. This was followed in 1996 with a historical version, Dark Ages: Vampire, set in medieval France around the year 1230.^[1] When Dark Ages: Vampire was revised and updated in 2002, White Wolf also released a number of supplements for other magical groups, including Dark Ages: Inquisitor, a 237-page softcover book written by Emily K. Dresner-Thornber, Myranda Kalis, Matthew McFarland, Anthony Ragan, Sarah Roark, Colin A. Suleiman, Adam Tinworth, and Janet Trautvetter.^[2] Artwork was provided by Jim DiBartolo, Marko Djurdjević, Eric Hotz, Becky Jollensten, Tom Mandrake, Rik Martin, Alex Sheikman, Adrian Smith, James Stowe, and Timothy Truman.^[3]

The book describes how players in Dark Ages: Vampire can create and play characters who are powerful members of a secret Shadow Inquisition, charged with discovering and destroying vampires and other "Get of Satan." The Inquisitor can be a member of one of five factions, each with special skills and magic.

Since many players of Dark Ages: Vampire join the game to play vampires and other non-human creatures, the Storyteller can alternatively use this book to create dangerous opponents who are actively seeking out the players in order to expose them and destroy them.^[4]

Peter Holian was impressed by the abilities granted to Inquisitors that gave them the power to stand up to a vampire or witch, saying, "I quite like Dark Ages: Inquisitor." Holian did feel this should have been a stand-alone game, commenting, "I was extremely annoyed that you need Dark Ages: Vampire to be able to run a game, whether you want it or not, because only it contains the core rules." Holian concluded, "All in all, this game embodies (even if it appears otherwise) what all the [World of Darkness] games historically entailed."^[5]
