Victor Sjöström (Swedish pronunciation: [ˈvɪktɔɾ ˈɧœˈstɾœm] ( listen); in the United States sometimes known as Victor Seastrom) (20 September 1879 – 3 January 1960) was a Swedish actor, screenwriter, and film director.

Born in Silbodal, in the Värmland region of Sweden, he was only a year old when his father, Olof Adolf Sjöström, moved the family to Brooklyn, New York. His mother died when he was seven years old in 1886. Sjöström returned to Sweden where he lived with relatives in Stockholm, beginning his acting career at 17 as a member of a touring theater company.

Drawn from the stage to the fledgling motion picture industry, he made his first film in 1912 under the direction of Mauritz Stiller. Between then and 1923, he directed another forty-one films in Sweden, some of which are now lost. Those surviving include The Sons of Ingmar (1919), Karin, Daughter of Ingmar (1920) and The Phantom Carriage (1921), all based on stories by the Nobel-prize winning novelist Selma Lagerlöf. They confirm him as one the very greatest of silent film directors, who helped to create a unique idiom with qualities quite different from those of sound cinema. Many of his films from the period are marked by subtle character portrayal, fine storytelling and evocative settings in which the Swedish landscape often plays a key psychological role. The naturalistic quality of his films was enhanced by his (then revolutionary) preference for on-location filming, especially in rural and village settings.
