Monster Mythology, published by TSR in 1992, is a sourcebook about non-human deities that can be used in fantasy role-playing games using the second edition rules for Advanced Dungeons & Dragons (AD&D).

"[1] It contains detailed information on the societies, cultures, myths, and deities of several non-human pantheons, including those of the elves, dwarves, gnomes, halflings, orcs, goblins, dragons, giants, drow, and many other creatures.

Keith Eisenbeis suggests the book can be thematically divided in two, with the first encompassing typical player character races, and the second detailing "gods of the major intelligent societal creatures".

This short appendix gives references where a Dungeon Master may find 2nd edition AD&D details on the deities of specific game worlds, such as the Forgotten Realms, Greyhawk, Dragonlance, and Dark Sun.

In the May-June 1993 edition of White Wolf Magazine (Issue 36), Keith Eisenbeis thought Monster Mythology was a "good product", but believed that the priests described were too powerful and unbalanced the game.
