The Nikaj-Mërtur region is a regional nature park in northern Albania, strategically inside the southeastern Albanian Alps in Tropojë. It lies within the area of the historical Nikaj and Mërturi tribes. The park is an area of alpine landscapes, deep valleys, vertical cliffs, dense coniferous and deciduous forests, small lakes and rivers. The International Union for Conservation of Nature (IUCN) has listed the park as Category IV. Like most of the Albanian Alps, it is listed as an important Plant Area, because it supports significant plant species.
