Game of Thrones City Name Generator

Westeros has only five true cities (King's Landing, Oldtown, Lannisport, Gulltown and White Harbor), so most settlements in A Song of Ice and Fire are market towns, ports and villages, and their names read like an English county map. George R. R. Martin builds them from a feature of the land plus a plain Old English ending: Fairmarket, Stoney Sept, Saltpans, Maidenpool, Duskendale, Bitterbridge, Tumbleton, Barrowton. Towns that grew up beside a castle simply borrow the castle's name, which is why there is a Wintertown below Winterfell and a Mole's Town south of the Wall.

Across the Narrow Sea the sound changes completely. The Free Cities carry clipped Valyrian and Rhoynish names (Braavos, Pentos, Myr, Lys, Tyrosh, Volantis, Qohor, Norvos, Lorath), Slaver's Bay uses Ghiscari names heavy on double vowels and harsh consonants (Meereen, Yunkai, Astapor), the Dothraki prefix every settlement with Vaes, the Rhoyne's dead cities hint at a lost tongue (Chroyane, Ny Sar, Ghoyan Drohe), and the far east drifts into Yi Ti and Asshai.

This list mixes every canon city and notable town from the books and show with hundreds of originals built the same way, so a custom settlement for fan fiction, roleplay or a mod sits naturally beside the real ones.
