Frostburn is a supplemental book to Dungeons and Dragons role-playing game (3.5 edition) that provides rules for adventuring in a cold environment as well as an environment known as frostfell, which is a sort of arctic environment with extreme (sometimes even magical) cold. This book follows two other books, "Sandstorm" and "Stormwrack", which also deal with specific environments.

The book contains information about cold and how it affect characters in the game, as well as various monsters, races, weapons, and spells that can be found in a "Frostfell" environment.
