In the Dungeons and Dragons World of Greyhawk campaign setting, the Ulek States refers to the three easternmost nations of the Sheldomar Valley. From north-to-south, they are the Duchy of Ulek, the County of Ulek, and the Principality of Ulek.
Though all three states are closely allied and often take the same position in international affairs, they are in fact three separate, sovereign nations, despite their names.
