Gallia Narbonensis (
Latin for "Gaul of
Narbonne", from its chief settlement) was a
Roman province located in what is now
Languedoc and
Provence, in southern
France. It was also known as
Provincia Nostra ("our Province"), from its having been the first Roman province north of the
Alps, and as
Gallia Transalpina ("Transalpine Gaul"), distinguishing it from
Cisalpine Gaul in northern Italy. It became a Roman province in the late 2nd century BC. Its boundaries were roughly defined by the
Mediterranean Sea to the south and the
Cévennes and
Alps to the north and west. The western region of Gallia Narbonensis was known as
Septimania.
