The Rzav (Serbian Cyrillic: Рзав) is a river in southwestern Serbia. The 62 km long left tributary to the Golijska Moravica river, it originates from two headstreams, the Veliki Rzav and the Mali Rzav. The river is sometimes referred to as the Golijski Rzav (Cyrillic: Голијски Рзав; Rzav of Golija) to distinguish it from another Rzav river in Serbia, the Rzav of Zlatibor.
The Mali Rzav (Cyrillic: Мали Рзав; Little Rzav) is the Rzav's shorter headstream. It originates from the northern slopes of the Mučanj mountain, near the village of Katići. Originally the river flows to the west, but at the village of Bjeluša it makes a large elbow turn, parallel to the even larger elbow turn of the Veliki Rzav. At the villages of Gornja Krušćica and Vranovina, the Mali Rzav straightens its course to the north and on the southern slopes of the Blagaja mountain meets the Veliki Rzav.
The Veliki Rzav (Cyrillic: Велики Рзав; Great Rzav) is the Rzav's longer headstream and sometimes it is referred to as just Rzav alongside its whole course. It originates from the southern slopes of the Murtenica mountain, southern extension of the Zlatibor mountain, in the northern part of the Stari Vlah region.
The Veliki Rzav originally flows eastward, next to the villages of Gornja Bela Reka and Donja Bela Reka (Serbian for upper white river and lower white river, referring to the river's clear water). At the village of Klekova the river sharply turns to the north, making a large elbow turn, beginning at the village of Velika, on the western slope of the Čigota mountain. Inside this elbow turn is the smaller curve of the Mali Rzav, and the two rivers get at one point less than 2 km apart. The Veliki Rzav receives from the left the Katušnica river and continues to curve to the north in the mountain region, between the villages of Razložina and Čičkovo, making another sharp elbow turn to the east, between the Lipovac and Gradina peaks, southeast of the town of Užice. After the village of Roge, the river continues on the southern slope of the Blagaja mountain, receiving the Mali Rzav from the right.
The remaining course under the name of the Rzav is less than 10 km long. It continues to the east as the natural extension of the Veliki Rzav around the Blagaja mountain, reaching the town of Arilje where it turns sharply for the last time, this time to the north, emptying into the Golijska Moravica.
