Susanna "Susan" Kohner (born November 11, 1936) is an American actress who worked in film and television. She is best known for her role as Sarah Jane in Imitation of Life (1959), for which she was nominated for an Oscar and won a Golden Globe award. She played a light-complexioned woman who "passed" for white as a young adult.

After Kohner married menswear designer and writer John Weitz in 1964, she retired from acting to devote time to her family. Her two sons, Chris Weitz and Paul Weitz, have both become film directors, screenwriters, and occasional actors.
