Mountains of the Moon is a 1990 American biographical film depicting the 1857–1858 journey of Richard Francis Burton and John Hanning Speke in their expedition to Central Africa, which culminated in Speke's discovery of the source of the Nile River and led to a bitter rivalry between the two men. The film stars Patrick Bergin as Burton and Iain Glen as Speke. Delroy Lindo appears as an African whom the explorers meet.

Captain John Hanning Speke was an English explorer and military officer who made three exploratory expeditions to Africa. He is most associated with the search for the source of the Nile and was the first European to reach Lake Victoria. Speke is also known for propounding the Hamitic hypothesis in 1863, in which he supposed that the Tutsi ethnic group were descendants of the biblical figure Ham, and had lighter skin and more Hamitic features than the Bantu Hutu over whom they ruled.
