Apnapan (transl. Kinship) is a 1977 Indian Hindi-language drama film, produced and directed by J. Om Prakash under the FILMYUG Pvt. Ltd. banner. It stars Sanjeev Kumar, Jeetendra, Reena Roy and Sulakshana Pandit, and has music composed by Laxmikant Pyarelal. The film is recorded as a Super Hit at the box office. This film was remade in Telugu as Illalu (1981).

Roy played a selfish gold-digger who abandons her husband and child, which garnered her critical acclaim and a Filmfare Award for Best Supporting Actress. However, she rejected the award citing that she was among the film's protagonists and not supporting actors, thus becoming the second actress (after Vyjayanthimala for 1955's Devdas) to decline a Filmfare Award.
