Ulken Koskopa (Kazakh: Үлкен Қосқопа; Russian: Большая Коскопа) is a salt lake in Nauyrzym District, Kostanay Region, Kazakhstan.
The lake is located 22 kilometers (14 mi) to the southwest of Mereke. Now abandoned Karasu village was located by the northern shore. The area is quite desolate, with few settlements.
The name Koskopa in the Kazakh language means "Double Kopa" —"Kopa" referring to a lake that seasonally becomes a salt marsh overgrown with reeds and sedges.
