Nothing but a Man is a 1964 American independent drama film starring Ivan Dixon and Abbey Lincoln, and directed by Michael Roemer, who also co-wrote the film with Robert M. Young. The film tells the story of Duff Anderson, an African-American railroad worker in the early 1960s who tries to maintain his dignity in a small racist town near Birmingham, Alabama, after he marries the local preacher's daughter. In addition to dealing with oppression and discrimination, Anderson must also come to terms with his troubled relationship with his own father, a drunk who abandoned and rejected him.

Although it was not widely seen upon release due to difficulties in finding distribution, the film is now generally considered to be an important example of neorealistic American cinema. In 1993, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
