The Isle of Dread is an adventure for the Dungeons & Dragons role-playing game. The adventure, module code X1, was originally published in 1981. Written by David "Zeb" Cook and Tom Moldvay, it is among the most widely circulated of all Dungeons & Dragons adventures due to its inclusion as part of the D&D Expert Set. In the adventure, the player characters search for a lost treasure, journey to the prehistoric Isle of Dread, and there meet new nonhuman races.

The Isle of Dread is meant to introduce players and Dungeon Masters familiar with only dungeon crawl-style adventures to wilderness exploration. As such, the adventure has only a very simple plot, even by the standards of its time. The module has been described as a medium to high level scenario, which takes place on a mysterious tropical island divided by an ancient stone wall.

The characters somehow find a fragment from a ship's log, describing a mysterious island on which many treasures can be found, and set out to explore it. Typically, the characters will first make landfall near the more or less friendly village of Tanaroa and after possibly dealing with some troublesome factions in the village, set out to explore the interior of the island. In the course of their explorations, they may find a number of other villages of unfamiliar intelligent creatures, numerous hostile monsters and the treasures they guard, and a band of pirates. Many prehistoric creatures, including dinosaurs, are prominently featured, especially in the original printing of the adventure. Near the center of the island is a hidden temple inhabited by monstrous, mind-bending creatures known as kopru; the characters may stumble across it or learn that it is a source of problems for the other inhabitants of the isle, and the climax of the adventure typically consists of the characters exploring this temple, battling its inhabitants, and uncovering its secrets.
