The Chirchiq or Chirchik (Uzbek: Chirchiq, Чирчиқ, Russian: Чирчик) is a river of Uzbekistan, a major right tributary of the Syr Darya.

Below, the valley widens and eventually joins the Syr Darya.

There are several dams on the river which serve both for electricity generation and irrigation.

All main canals of Tashkent, such as Bozsu, Anhor, Salar, and Burijar are fed by the water from Chirchik.

The river flows through or in close proximity to the cities Xoʻjakent, Gʻazalkent, Chirchiq, Tashkent, Yangiyoʻl, and Chinoz.
