Greyhawk, also known as the World of Greyhawk, is a fictional world designed as a campaign setting for the Dungeons & Dragons fantasy roleplaying game. Although not the first campaign world developed for Dungeons & Dragons—Dave Arneson's Blackmoor campaign predated it by about a year—the world of Greyhawk closely identified with early development of the game beginning in 1972, and after being published it remained associated with Dungeons & Dragons publications until 2008.
