Kwilu is a province of the Democratic Republic of the Congo. It's one of the 21 provinces created in the 2015 repartitioning. Kwilu, Kwango, and Mai-Ndombe provinces are the result of the dismemberment of the former Bandundu province. Kwilu was formed from the Kwilu district and the independently administered cities of Bandundu and Kikwit. Bandundu is the provincial capital. The 2020 population was estimated to be 6,682,300.

The province takes its name from the Kwilu River, which crosses it from the southeast to the northwest.

Towns and territories are:

• Bagata
• Bulungu
• Gungu
• Idiofa
• Mangai
• Masi-Manimba

Kwilu was administered as a province from 1962 to 1966. However, in 1964 the administration was taken over by the central government due to a rebellion in southwestern Congo. A rebel administration under Pierre Mulele ran most of Kwilu province from January 1964. The province was reconquered by the legal government in June 1965. The provincial government was restored on January 18, 1966, but the province was merged with Kwango District and Mai-Ndombe District to create Bandundu Province.
