Jormungar are enormous worms that can be encountered in Northrend in World of Warcraft: Wrath of the Lich King. They have muscular, flattened bodies with rows of crystalline spines along either flank.
According to the frost vrykul the Jormungar are the children of the titanic watcher . Further legends tell of the nerubians' using the jormungar as creatures of labor, forcing them to carve massive tunnels through Northrend's subterranean ice and lay the groundwork for the nerubians' ancient civilization. With the fall of the nerubian empire, swarms of rogue jormungar ran amok, drilling through the region's permafrost, attacking surface dwellers, and devouring everything in their path. The jormungar no longer appear to serve the nerubians, undead or otherwise, in any capacity. However, Scourged Burrowers are similar creatures with a similar function for them.
A massive jormungar the size of attacked the group of Frostborn dwarves who had found close to death. After swallowing a dwarf whole, the dwarves began to fear. Muradin, despite his wounds, became an Avatar and threw his hammer at the beast, killing it, and nearly taking its head off.
The fiercely aggressive jormungar are a marvel of evolution, possessing rows of chisel-like teeth capable of boring through solid rock, as well as muscular, flattened bodies well adapted to rapid underground navigation. They have ice-cold, acidic blood which was once collected by the nerubians. The jormungar have perhaps the strangest diet; they grow strong by eating the eggs of their own kind and the best eggs come from deep jormungar.
Each brood has a spawnmother living deep underground. The jormungar are a nuisance best dealt with quickly. If given any quarter, they breed like hares and spread like fire. There are multiple stages of jormungar: The egg sac, what the is, the regular jormungar (called a jormungar larva in the model flies), and the jormungar wyrm (called just a jormungar in the model files). The wyrm stage is more ruggedly featured, and partially submerged at all times (with some exceptions). Before the above bestiary entry was added, the name of the unrevealed race as a whole was "jormungar wyrm".

- The rockworms found on Draenor use the same models as jormungar.
- Some of the giant worms used as companions and mounts by the drogbar of Highmountain also use the same models as jormungar. It is unclear if these worms are actual jormungar (as the Broken Isles are located quite close to Northrend), relatives of the jormungar or if it is simply a case of model reuse.
