The Vitii were a tribe that in antiquity lived in the former Caucasus Albania; in and around a town now known as Nij, in the Qabala district of Azerbaijan. While some scholars believe that the Vitii were indigenous Caucasus Albanians, and possibly ancestral to, or neighbours of the Udi people who now live in the Nij area, there are numerous theories suggesting that the Vitii originated with another people, who settled in the area in antiquity.
