Nevesinje (Serbian Cyrillic: Невесиње) is a town and municipality in Bosnia and Herzegovina, located in eastern Herzegovina, between Mostar and Gacko. It is administratively part of the Republika Srpska entity.

The municipality of Nevesinje is located in southern part of Bosnia and Herzegovina. This mountaneus municipality covers 1,040 km² (402 sq mi) and average elevation is 860 m above the sea level. A large Karst plain dominates the municipality.

The annals of the Patriarchal Monastery of Peć mentioned Nevesinje in 1219, which is the earliest appearance of Nevesinje in preserved historical sources. The župa (county) of Nevesinje was held by Serbian prince Stefan Konstantin between 1303–06.

The Nevesinje region was under the rule of different medieval lords until the end of the 15th century. The most significant ruler of Nevesinje from this period was Stjepan Vukčić Kosača, known as Herceg Stefan. The whole land Hercegovina was named after him. His lands were under the constant threat from advancing Turkish forces in the 15th century. Hercegovina, and thus Nevesinje were gradually incorporated into the Turkish Empire by the first quarter of the 15th century (1422).

During the period of Turkish rule Nevesinje was mostly part of Bosnian Pashaluk and was a seat of a qadi. It was at Nevesinje that the Great Eastern Crisis was ignited, with the outbreak of the Herzegovinian rebellion of 1875-78 when Serbs of the region rebelled against Turkish tax collectors. The rebellion soon spread to the rest of Herzegovina and to Bosnia and other parts of the Ottoman Empire.
