Lemba is a commune in the Mont Amba District of Kinshasa, the capital of the Democratic Republic of the Congo.

[3] The eastern boundary follows the Matete River upstream to its source, connecting via a straight line to the southeastern corner of the University of Kinshasa's concession.

With 206,900 on its voter rolls Lemba is an electoral district for both the election of an eleven-member communal council and that of two deputies of the Provincial Assembly of Kinshasa.

Peter Kazadi Kankonde (UDPS/Tshisekedi) and Yvette Lubala Nazinda (AA/a) are the deputies representing Lemba in the new legislature.

The name Lemba originates from the Humbu people, a Bantu-speaking ethnic group, and means "owners of the banks and lands to the south of the Pool Malebo".

[17] It served as a key marketplace where traders from the upper and lower Congo River regions gathered, notably near a baobab tree that once stood on the present-day grounds of the University of Kinshasa.

The Franciscan missionary Girolamo Merolla da Sorrento, who arrived in the Congo in 1683, provided one of the earliest accounts.

[18][19] In the late 19th century, the Welsh-American explorer Henry Morton Stanley also described Lemba as a major commercial hub during his travels.

[17] During the colonial period, the territorial organization of Lemba was shaped by the royal decrees of 1 July 1897, which established administrative structures across the province of Léopoldville (modern-day Kinshasa).
