My Heart of Darkness is a Swedish–German 2010 documentary film about four ex-soldiers from different sides of the Angolan civil war and their posttraumatic stress disorder. The film was recorded in 2007. It was first shown at the International Documentary Film Festival Amsterdam on November 20, 2010. It premiered in Sweden on April 8 the next year. The title of the film is a reference to Joseph Conrad's novella Heart of Darkness. The film, like the novella, takes place on a boat traveling up an African river, and covers issues of tragedy and abuse.

The four ex-soldiers do not all speak the same language, but translate for each other. The narrator Marius van Niekerk, who is also the film's director and lead character, speaks English, while the others speak Portuguese and Afrikaans.
