Loznica (Serbian Cyrillic: Лозница, pronounced [lǒznitsa]) is a city located in the Mačva District of western Serbia, on the right bank of the Drina river.

The oldest settlements on the territory of Jadar and Loznica can be traced to the Neolithic period when the Starčevo culture flourished from 4500–3000 BC.

Legend tells that Loznica was named after the grape vines that were grown in this region, starting from the 3rd century BC in the time of Roman Emperor Probus.

This resulted in the abolition of Ottoman ownership over the land and it was declared a free peasant state, which meant that the feudal system was revoked.

When hot air from Adriatic Sea starts going inland, to the north-east it rises over mountain barriers (Zlatar and Zlatibor), gaining jet effect and continuing fast to western parts of Serbia.
