Nanook of the North (also known as Nanook of the North: A Story Of Life and Love In the Actual Arctic) is a 1922 silent documentary film by Robert J. Flaherty. In the tradition of what would later be called salvage ethnography, Flaherty captured the struggles of the Inuk Nanook and his family in the Canadian arctic. The film is considered the first feature-length documentary, though Flaherty has been criticized for staging several sequences and thereby distorting the reality of his subjects' lives.
In 1989, this film was one of the first 25 films to be selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
