Ersekë (Definite Albanian form: Erseka) is a town in southeastern Albania. Founded in the 17th century, Erseka is the capital of the Kolonjë District. Situated at the foot of the Gramos mountains, it is a small alpine town at 1050 meters in altitude, making it one of the highest towns in Albania.

The Kolonja range was originally inhabited by the Dassaretae, a Greek tribe that belonged to the Chaonian group.

The history of the town began at the 17th century. At 1785 city was populated from 100 families. At 1914 it came under the control of the Northern Epirote forces, which repelled the newly established Albanian gendarmerie units from the region.

The "Fan Stilian Noli" center hosts several artistic and cultural shows throughout the year. Its main theater of 400 seats hosts performances by various groups from Korçë, Tirana and local artists. The ethnographic museum also houses a collection of traditional costumes, textiles and other crafts, unique to the Erseka region.

In the center of the town is an obelisk, work of Odhise Paskali, which dates 28 November 1938.
