The Upemba Depression (or Kamalondo Depression) is a large marshy bowl area (depression) in the Democratic Republic of the Congo comprising some fifty lakes, including 22 of relatively large size including Lake Upemba (530 km²) and Lake Kisale (300 km²). In an earlier era, the area was probably occupied by one large lake.

The area is covered in marshland and is partially within the Upemba National Park in Haut-Lomami District. The Upemba Depression has been populated almost continuously since the 5th century AD, and is considered the origin of the Kingdom of Luba (1585-1889). Chronology based on more than 55 radiocarbon datings and thermoluminescence shows periods of occupation since the Stone Age. The area includes many archaeological sites, such as the Kisalian Graves, and is on the tentative list for UNESCO World Heritage Site.^[2] Roughly translated, the citation for its inclusion as World Heritage Site states:

This large depression has delivered the largest known cemetery in sub-Saharan Africa. Over 40 archaeological sites have been identified, but only six have been partially excavated so far. Their study allows tracing the complete sequence of the occupation of the region over two millennia, and thus reconstructing the history of a major ethnic group of Central Africa: the Luba.
