Lutetia (also Lutetia Parisiorum in Latin, Lukotekia before, in French Lutèce) was a town in pre-Roman and Roman Gaul.

Lutetia and Paris have little in common save their position where an island, the Île de la Cité, created a convenient ford of the Seine.

Bibracte, *bibro 'beaver' + -acti = 'the beavers') or another Celtic root luto-, luteuo- 'marsh', 'swamp' (Gaelic loth 'marsh', Breton loudour 'dirty') like in Lutudarum (Derbyshire, England); Lodève (Luteua); Ludesse (France); Lutitia (Germany), etc.
