Gnomeregan (or the Nation of Gnomeregan) is the city-state of the gnomish race in Azeroth, located in Dun Morogh. It has traditionally been closely allied with the Bronzebeard Clan of the Kingdom of Ironforge. The city was recently irradiated and invaded from within by mutated troggs, forcing its people to establish a new foothold above ground.

It is headed by the High Tinker of Gnomeregan. The current capital is New Tinkertown.
