The Saryozen (Kazakh: Сарыөзен), also known as Konyrauli (Kazakh: Қоңыраулы), is a river in the Zharkain District of Akmola Region and the Amangeldi and Zhangeldi districts of Kostanay Region, Kazakhstan.

Finally it enters lake Sarykopa from the northeastern end.

In years of high water the Saryozen river may flow across lake Sarykopa into the Turgay through a channel near Tauysh village.

Its main tributary is the 133 km (83 mi) long Ulken Damdi from the right.
