The Zeta (Montenegrin Cyrillic: Зета, pronounced [zêta]) is a river in Montenegro.

Its drainage basin area is 1,597 km2 (617 sq mi).

[1] One theory is that the name "Zeta" derives from an early Greek "Zenta", later romanized in "Senta".

After that, the river meanders through the Bjelopavlići Valley and Danilovgrad Municipality, until it empties into the Morača a few miles north of Capital City of Podgorica.

Historical monumental Carev Most (the Tsar's Bridge) exists over Zeta to the south of Nikšić town, and the ancient castle of Pandurica is situated nearby.
