Celtic cities are cities that can be founded by the Celtic civilization in Civilization V and its expansions. The first city founded is the Capital5 Capital, and the names of future cities are chosen in the order they appear on the list below.

The names listed are default names; players can change their cities' names if they choose.

Celtic city names are drawn from the six modern "Celtic nations" of Scotland, Ireland (Republic of Ireland and Northern Ireland), Wales, Cornwall, Brittany and the Isle of Man. They appear in that order, with the first being Scottish, the second Irish, the third Welsh, and so on.
