- Argus, the homeworld of the eredar race of magic-wielders and their exiled brethren called the draenei. Now the stronghold of the Burning Legion, located on the border between the Great Dark and Twisting Nether.
- Centralis, a world where all its inhabitants were slaughtered by Gorelix and the Maw of the Dammed.
- Draenor (Outland) was the homeworld of the orcs, ogres, and other species, and a sanctuary of the draenei. It was destroyed in a cataclysm. The remains of Draenor, called Outland, are no longer considered to be a planet as it sits between dimensions.
- Dreadscar Rift, a Legion portal-world previously controlled by Mephistroth and ruled by the Pitlord Jagganoth. The warlocks of the Black Harvest took control of this world. It is in the Twisting Nether.

- Mardum, a prison world created by Sargeras in the Twisting Nether when he still served the titan Pantheon. The imprisoned demons became the first members of the Burning Legion when Sargeras returned and shattered Mardum. The demons had used Mardum as a portal-world ever since as well for guarding the , until they were defeated by the Illidari, who then took control of Mardum for themselves.
- Nathreza, the homeworld of the nathrezim. It is located in the Twisting Nether.
- Navane, a world with a handful of intelligent races who held a history of enmity but united against the Burning Legion. Kathra'natir turned them against each other.
- Nihilam, the "Doom World", is a planet near where the Pantheon confronted Sargeras after the Burning Legion's first destruction of a world. Sargeras proceeded to kill his fellow titans when they tried to reason with him, and Nihilam became twisted and warped by the apocalyptic conflict.
- Niskara, another Legion portal-world, home to the Niskaran inquisition.
- Xandros, a world destroyed by Mongrethod, who was sent by the Burning Legion, and now inhabits the remains.

- An unknown world depicted in the Halls of Lightning, with two green / white continents; one in its southern hemisphere and another in its northern hemisphere and a third purely white continent / ice cap that centers around the world's equator. It is mostly covered in water.
- Several other seemingly gaseous planets seen in the skies of Outland and that are depicted in the Halls of Lightning and Ulduar.
- Many worlds that were judged and observed by Algalon the Observer during his mission from the titans.
- Countless other unnamed worlds have been visited by the titans, the naaru, and taken over or obliterated by the Burning Legion.
- The draenei passed dozens of worlds and mapped much of the cosmos after they left Argus.
- After the Dark Portal was destroyed, Draenor began tearing itself apart. Turalyon led the forces of the Alliance Expedition that were with him through a portal to yet another world, one they could barely make sense of. After the set of cataclysmic events that changed Draenor into Outland were over, Turalyon, Alleria, Khadgar, Danath and the other Alliance troops all returned to Draenor, now called Outland.
- At least seven planets are set to feature in future patches and/or expansions for World of Warcraft, courtesy of Outland's Dimensional Gateways.
- Illidan traveled to three worlds destroyed by the Burning Legion while seeking out Nathreza:
- A desert with cemetery cities with bodies clogging the streets. Imps danced among the ruins. War had sliced the tops of hills and turned plains into sheets of glass. Mad ghosts haunted the land and mountains had been carved in the shape of dreadlords. A moat of bones surrounded a city the size of a nation. A giant skeleton rose from the moat and clawed its way over mountains of bones before the necromancy faded and the giant collapsed.
- An ocean world with the water red as blood, filled with poisons that killed the whale-sized inhabitants. Massive rafts woven from dead kelp rotted on the surface with corpses of merfolk entwined around them. Sea creatures the size of cities decomposed on the ocean floor, surrounded by skeletons of aquatic armies that had once guarded them.
- A desert world where he found the bones of wandering tribespeople. Every oasis had been poisoned. Dunes sometimes crumbled to reveal the skeletons of armored worms or remains of brass skyscrapers.
- Illidan Stormrage and his demon hunters traveled to a demon world under the control of the pit lord Azgoth.
- An unknown number of demon worlds have been invaded by the Class Orders in an attempt to take them as their own.
- The demons of the Burning Legion transcend a near infinity of universes and destroy their possible worlds.
- According to Illidan, there are only several worlds left, besides Azeroth and Outland, that were not completely annihilated by the Burning Legion. After the events of the war in Draenor, the alternate Draenor is saved too.
- Yet according to Wrath-Lord Lekos, Azeroth is the last world standing, whether the demon meant it literally or just boasted is unclear.
- The term "world" generally refers to Azeroth itself, other worlds are generally referred to by their names in context to Azeroth.
- Azeroth and Draenor orbited different kinds of stars. Azeroth has a single yellow sun, whereas Draenor had a single red sun.
- Draenor's cataclysmic destruction would have been seen from Azeroth, but there is no mention of anyone observing it.
In the World of Warcraft The Burning Crusade Official Strategy Guide, Azeroth is said to be the "closest habitable world" to Draenor by dimensional travel.
Travel between worlds
The only known means of traveling between worlds is through the use of magic, or through advanced technology. These include:
- Dimensional Gateways, such as the Dark Portal, and other portals fueled by various forms of magic.
- Dimensional Ships, such as Tempest Keep.
