Grbalj (Montenegrin and Serbian Cyrillic: Грбаљ) is a historical region, Serb tribe, a field between Budva and the Luštica peninsula, in seaside Montenegro. It is a fertile region surrounded by the Lovćen to the east, and to the west the low hills separate the region from the Adriatic.
In the east frontier of the field, ten villages have developed, collectively referred to as Upper Grbalj. Lower Grbalj constituted the villages on the western edge of the field. The Bigova village, situated in a cove with the same name, is the only place on the coast.
Villages located in Grbalj are Bigova, Bratešići, Višnjeva, Vranovići, Glavati, Glavatičići, Gorovići, Dub, Zagora, Kovači, Krimovica, Kubasi, Lješevići, Nalježići, Pelinovo, Pobrđe, Prijeradi, Sutvara, Trešnjica, Ukropci, Šišići and Mačić.
The Adriatic highway goes through Grbalj. After its construction, and the 1979 earthquake, several settlements were established along it.
The region is an important agricultural area. The southern part of the field consists of orchards, vineyards and vegetable gardens. This part of the field ends with the Jaz beach. In the northern part of the Grbalj field, lies the industrial area of Kotor.
Grbalj was a župa (county) of the medieval Serbian state under the Nemanjić dynasty. It was the personal estate of Stefan Vukanović Nemanjić (fl. 1252).
In 1497 Firuz Beg captured Grbalj and put Zeta under his effective military control, although it was still part of the Zeta governed by Stefan II Crnojević.
