The Srebarna Nature Reserve (Bulgarian: Природен резерват Сребърна, transliterated as Priroden rezervat Srebarna) is a nature reserve in northeastern Bulgaria (Southern Dobruja), near the village of the same name, 18 kilometers (11 mi) west of Silistra and two kilometers (1.2 mi) south of the Danube.

It comprises Lake Srebarna and its surroundings, and is an important wetland located on the Via Pontica, a bird migration route between Europe and Africa.

While Lake Srebarna was studied many times in the past by foreign biologists, the first Bulgarian scientist to take an interest in the area was Aleksi Petrov, who visited the reserve in 1911.

In 1913, the whole of Southern Dobrudja was incorporated in Romania, but was returned to Bulgaria in 1940, when the area was visited once again by Petrov to examine the colonies of birds that nest there.

The one is about a khan named Srebrist, who died in the neighbourhood whilst engaging in an unequal battle with the Pechenegs.
