The Isfara is a river of the Syr Darya basin in Kyrgyzstan, Tajikistan and Uzbekistan.

30 km (19 mi) further north, the river reaches the border with Uzbekistan at Rabot.

The Isfara formed an alluvial cone north of Rabot.

Today, the incoming river water is directed to the Great Fergana Canal to the northeast.
