Eldritch Wizardry is a supplementary rulebook by Gary Gygax and Brian Blume for the original edition of the Dungeons & Dragons fantasy role-playing game. It was published by TSR, Inc. in 1976 as the third supplement to the original Dungeons & Dragons boxed set and bears the designation "Supplement III", with supplements Greyhawk and Blackmoor having been released in the previous year. Its product designation was TSR 2005.
This 60-page supplement is particularly notable for having introduced the concepts of demons (and their lords Orcus and Demogorgon), psionics (and monsters who use psionics, most famously the mind flayers), artifacts (such as the Rod of Seven Parts and the Axe of the Dwarvish Lords), and the druid as a character class, to the Dungeons & Dragons game.
Illustrations were provided by David C. Sutherland III, Tracy Lesch, and Gary Kwapisz, with a cover by Deborah Larson. The booklet was edited by Tim Kask.
