Legio VI Hispana: one of the legions of the later Roman empire. Its name means "Spanish legion".
The existence of this legion is proven by a mid-third century inscription from Aquileia that mentions that the signifer (an officer) of the Sixth Legion Hispana dedicates something to the god Mithras. It is perhaps possible to date this inscription to the reign of Philippus Arabs (r.244-249).
The number was probably derived from another legion in Spain, VII Gemina.
