Lothar Stark (1876–1944) was a German film producer. Stark was originally a journalist, but was brought into the film industry by the tycoon Paul Davidson. Stark worked as an independent producer during the Weimar Republic, founding his own company Lothar Stark-Film. Following the Nazi takeover in 1933, he faced increasing difficulties. In 1933 when evidence of his Jewish background was discovered, Stark went into exile in Copenhagen. Later he also went to London.
