Goygol National Park, Protected nature reserve in Goygol Rayon, Azerbaijan.

Göygöl National Park covers 12,755 hectares on the northeastern slopes of the Lesser Caucasus, centred on Lake Göygöl at 1,553 m. The lake, about 80 ha with a maximum depth of 93 m, sits in the Kürəkçay basin and is joined by Zelilgöl, Maralgöl and Qaragöl. Deep valleys cut the terrain, which rises to Mount Kəpəz, and oak, alder and poplar forests cover the slopes.

Göygöl State Nature Reserve was established in 1925 as Azerbaijan's first protected area. It was abolished in 1950 and 1961, then re-established in 1965 by a decree of the Council of Ministers of the Azerbaijan SSR. On 1 April 2008, a presidential order transformed it into Göygöl National Park, covering 12,755 hectares.

The name Göygöl means "blue lake" in Azerbaijani. The lakes were formed by the 1139 Ganja earthquake, and the reserve was created in 1925 to protect the drinking water of Lake Göygöl. A 2015 documentary about the park was part of the "9 Wonders of Azerbaijan" project led by Leyla Aliyeva.

The park lies on the north-eastern slopes of the Lesser Caucasus in Göygöl district, with altitudes from 1,100 to 3,065 m and Mount Kyapaz as the highest point. Göygöl lake itself sits at 1,553 m, reached by road from the district centre; the reserve's Eldar pine branch lies separately on the Elleroglu ridge at 710 m. Expect dry cold winters and 600–900 mm of annual precipitation.

The park shelters rare birds of prey including bearded vultures that nest in mountain crevices and soar above the valleys. These raptors have become uncommon in many mountain regions and rely on areas like this for survival.
