Upper Zeta (Serbian: Горња Зета/Gornja Zeta) is a historical region in Montenegro, roughly between the Morača and Zeta rivers. During the Middle Ages the province of Upper Zeta was part of the Serbian state under the Nemanjić dynasty, existing alongside Lower Zeta. It was then held by the Balšić and Crnojević families until the Ottoman annexation (1514). In the late modern period, the term was used for an area in the northern half of "Old Montenegro", though its borders fluctuated.
