Fier County (Albanian pronunciation: [fieɽ]; Albanian: Qarku Fier), officially the County of Fier (Albanian: Qarku i Fierit), is a county in the Southern Region of the Republic of Albania. It is the eighth largest by area and the third most populous of the twelve counties, with about 240,000 people within an area of 1,890 km (730 sq mi). The county borders on the Adriatic Sea to the west, the counties of Tirana to the north, Elbasan to the northeast, Berat to the east, Gjirokastër to the southeast and Vlorë to the south. It is divided into six municipalities, Fier, Divjakë, Lushnjë, Mallakastër, Patos and Roskovec, all of whom incorporate 42 administrative units.

Until 2000, Fier County was subdivided into three districts: Fier, Lushnjë, and Mallakastër. Before 2015, it consisted of 42 municipalities.

Fier County maintains a relatively strong economy within Albania with agriculture and heavy industry serving as a backbone of the area during the communist era. Wages in the county are above the Albanian average. More recently, a service-based economy has become more prominent locally as well as small-scale manufacturing by foreign companies.

Fier additionally has been the home of power-generation in Albania with the construction of the Fier Power Plant during the communist era. Although it was decommissioned in 2007, a joint Greek-Albanian venture was announced in 2023 to revitalize these thermal plants to diversify Albania’s electrical industry.
