The Sileti (Kazakh: Сілеті; Russian: Силети) is a river in Kazakhstan.

It flows roughly northeastwards in its upper and middle course, parallel to the Teneke.

As it reaches its last stretch the river divides into branches and bends northwards to the west of lake Zhalauly.

[2][1][3] The main tributaries of the Sileti are Koyandy, Akzhar, Zhartas, Kedey, Sholakkarasu and Shili.

Its reservoir provides water to Stepnogorsk city, located 140 km (87 mi) to the north.
