Paris

capital of France, from Gallo-Latin Lutetia Parisorum (in Late Latin also Parisii), name of a fortified town of the Gaulish tribe of the Parisii, who had a capital there; literally "Parisian swamps" (see Lutetian).

The tribal name is of unknown origin, but it is traditionally derived from a Celtic par "boat" (perhaps related to Greek baris; see barge (n.)), hence the ship on the city's coat of arms.
