Zyuratkul (Russian: Зюраткуль; Bashkir: Йөрәккүл) is a freshwater lake in Satkinsky District, Chelyabinsk Oblast, Russia.

[3] In 1993 the Zyuratkul National Park, a protected area, was established in the lake and its surroundings.

It is located about 5 km (3.1 mi) to the south of the small mountain range named after it.

Its southern shore stretches at the feet of the northern slopes of the larger Nurgush range.

After WWII a dam was built and the new reservoir doubled the surface area of the ancient lake.
