'''Bolshoy Uzen''' ({{lang-kk|''Үлкен Өзен''}}, {{lang-ru|''Большой Узень''}}) is a river in [[Saratov Oblast]] of [[Russia]] and [[West Kazakhstan Province]] of [[Kazakhstan]]. It is {{convert|650|km|mi}} long, with a [[drainage basin]] of {{convert|15600|km2|mi2}}. 

The Bolshoy Uzen has its sources on the western edge of the [[Obshchy Syrt]] highlands of Russia, and flows in a generally southerly direction over the [[steppe]]s of the [[Caspian Depression]]. It terminates in West-Kazakhstan, in a network of small lakes and swamps called the [[Kamysh-Samarskiye Lakes]]. The Bolshoy Uzen runs parallel to the [[Maly Uzen River]], some {{convert|50|km|mi}} further west.

Most of the river's waters comes from [[snowmelt]], so the river's flow peaks in April, while in the summer parts of the river will dry up completely. At Novouzensk the discharge varies from {{convert|7.3|to|393|m3/s|cuft/s}}. The river freezes over in December and stays icebound to the end of March or the beginning of April. 

The town of [[Novouzensk]] is situated at the Bolshoy Uzen. The river is used for water supply and irrigation.
