D&D Kingdom Name Generator

Kingdom names in Dungeons & Dragons carry a lot of weight for very few syllables. Look at the Forgotten Realms: Cormyr, Amn, Tethyr, Sembia, Thay, Damara. Most are two or three syllables, end in a soft vowel or a consonant like -r or -n, and sound like they were worn smooth by centuries of use. Greyhawk does the same with Furyondy, Keoland and Nyrond. The lesson for DMs is that a real-sounding kingdom name is short, easy to say, and does not describe itself: nobody in-world calls their homeland Shadowfen.

That said, D&D maps also use descriptive and titled forms, and they signal government type at a glance. "Kingdom of Aldreth" implies a single crown; "Duchy of Harrowmere" or "Free Marches of Tenmoor" implies a smaller or looser polity; "The Iron Concord" or "The Silvergate Compact" suggests a league of city-states; and "The Old Empire of Tyrr" tells players there is a fallen power whose ruins are worth exploring. Mixing forms across your map makes the world feel politically varied.

When picking a name, think about who founded the realm. A kingdom named after its first king (Osric, Torvald), a river, a mountain range or a founding people will feel more grounded than one named for a mood. Then decide what neighbours call it; a rival kingdom rarely uses the polite official name.
