World of Warcraft Classic brings back World of Warcraft as it was before The Burning Crusade. Blizzard launched it on 26 August 2019, built on patch 1.12.1 from 2006: a level cap of 60, the old talents, the old raids and the old slow levelling.

Classic has since grown into several branches. Beyond the original era, the progression servers moved through Burning Crusade, Wrath of the Lich King and Cataclysm up to Mists of Pandaria Classic in 2025. There is a one-life Hardcore mode, the rune-based Season of Discovery and anniversary realms. At BlizzCon 2026 Blizzard announced World of Warcraft: Forever, a Classic+ version with new zones and systems.

It suits players who want slow levelling and guild raids. It needs the standard WoW subscription, and Blizzard has not sold games or game time in Russia since March 2022.
