Gallic, derived from the name for the ancient Roman province of Gaul, describes the cultural traditions and national characters of the French speaking nations and regions, as Hispanic does for the Hispanophone world, Anglo-Saxon for the Anglophone, and Lusitanic for the Lusophone. Like those other terms, Gallic, as a linguistic-cultural term, transcends race and ethnicity. Some important Gallic regions include France, Wallonia, Haiti, and Quebec.

While Gallic is used as a linguistic-cultural term, it is also used as a synonym for Celtic, as Gaul was the heartland of ancient Celtic culture.
