科托罗斯尔河是俄罗斯的河流，位于雅罗斯拉夫尔州，属于伏尔加河的右支流，发源自罗斯托夫附近，在雅罗斯拉夫尔注入伏尔加河。由于科托罗斯尔河与俄罗斯其他河流相连，因此在中世纪时有战略重要性。

The Kotorosl River (Russian:Ко́торосль) is a right tributary of the Volga in the Yaroslavl Oblast of Russia. The river flows from Lake Nero near Rostov past Karabikha and enters the Volga in Yaroslavl. In the medieval ages, the river was highly important strategically, for it connected Rostov with major waterways of Russia. The Kotorosl's main tributary is the Ustye River, which flows past Semibratovo to Borisogleb.
