Dungeons & Dragons (abbreviated as D&D or DnD) is a fantasy role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson, and first published in 1974 by Tactical Studies Rules, Inc.

As of 2006, Dungeons & Dragons remains the best-known and best-selling role-playing game, with an estimated 20 million people having played the game and more than US$1 billion in book and equipment sales. Dungeons & Dragons is known beyond the game for other D&D-branded products, references in popular culture and some of the controversies that have surrounded it, particularly a moral panic in the 1980s falsely linking it to Satanism and suicide.
