The Vertamocorii ( Gaulish: *Wertamocorī) were a Celtic people that lived in Cisalpine Gaul around Novara, in Eastern Piedmont ( Italy).
The Vertamocorii are reported by Pliny in the third book of Naturalis Historia, where they are said to be the founders of the city of Novara:
Novara (founded) by the Vertamocorii, that are from the Vocontii, and not, as believed Cato, Ligurians, ... [1]
and indicates their Gaulish origin (the Vocontii were a people of Gallia Narbonensis) and not Ligurian.
