Curse of Xanathon is a Dungeons & Dragons module, coded X3, designed by Douglas Niles for use with the Expert D&D set.

Lawrence Schick, in his sourcebook of roleplaying games, Heroic Worlds, describes it as a town adventure in which the players are tasked with solving a mystery in order to remove a curse[1].

The module received 7 out of 10 in a review in Issue 48 of White Dwarf magazine. It was not deemed as good as the current releases for Advanced Dungeons & Dragons at the time, but better than the preceding Castle Amber (Dungeons & Dragons).[2]
