Mwinilunga is a town in the North-Western Province of Zambia. It is the headquarters of Mwinilunga District, one of the province's eleven districts.

The town lies on the west bank of the West Lunga River, along the Chingola–Solwezi–Mwinilunga Road (T5 Road of Zambia), which continues north-westwards to Caianda, in Angola. Mwinilunga is located approximately 275 kilometres (171 mi), by road, west of Solwezi, the provincial capital. Another tarmacked state road (D286 Road of Zambia), leads south to Kabompo, the capital of Kabompo District. Kabompo town is approximately 247 kilometres (153 mi) south of Mwinilunga.

Mwinilunga sits in the extreme north-western corner of the country, close to the international borders with Angola and the Democratic Republic of the Congo. The geographical coordinates of Mwinilunga, Zambia are:11°43'02.0"S, 24°25'44.0"E (Latitude:-11.717222; Longitude:24.428889). The average elevation of the town is 1,391 metres (4,564 ft) above mean sea level.

This is one of the wettest places in Zambia with annual rainfall of about 1,400 millimetres (55 in) falling in the rainy season from October to May.

Due to its proximity with Angola and DR Congo, Mwinilunga would have benefited from trade with the two neighboring countries. Poor roads, human conflict and lack of collective political will in the three countries, have so far prevented any meaningful trade policy from developing. The Zambezi River originates in Ikelenge District, in a community called Kalene Hill, approximately 80 kilometres (50 mi) north of Mwinilunga town.

The town had a population estimated at 14,500 in 2006. The Chilunda-speaking Kanongesha-Lunda people are the largest ethnic group, and are related to the Chibemba-speaking Kazembe-Lunda of Luapula Province.

In 2006 plans were formulated to extend the proposed railway to Solwezi to the town and even on to the Benguela Railway in Angola to avoid reliance on the line in the DR Congo, but these plans have not been confirmed and the Benguela Railway has not yet been re-opened. However, the Angolan transport ministry plans to build a line branching off the Benguela Railway at Luacano and entering Zambia from Macango, Angola. The town is also home to Mwinilunga Airport.
