This is a list of deities of Dungeons & Dragons, including all of the 3.5 edition gods and powers of the "Core Setting" for the Dungeons & Dragons (D&D) roleplaying game. Religion is a fundamental element of the D&D game, because it is required to support both the cleric class and the behavioural aspects of the ethical alignment system. The pantheons employed in D&D provide a useful framework for creating fantasy characters, as well as governments and even worlds. Because the Core Setting is based on the World of Greyhawk, the Greyhawk gods list contains most of the deities listed here, and many more.
