Deiva Magan ( transl. Divine Son) is a 1969 Indian Tamil-language drama film written and directed by A. C. Tirulokchander. An adaptation of the Bengali novel Ulka by Nihar Ranjan Gupta, it stars Sivaji Ganesan in three roles and Jayalalithaa, with Sundarrajan, M. N. Nambiar, Nagesh, V. Nagayya and Pandari Bai in supporting roles. The film is about a scarred man who attempts to reconnect with his estranged family.

Following the 1957 film Ulka, Thayi Karulu (1962), Meri Surat Teri Ankhen (1963) and Thayin Karunai (1965), Deiva Magan is the fifth film adaptation of the novel. Its screenplay was written to be largely different from those of the earlier films, most of which were poorly received. The film was produced by Periyanna of Shanthi Films, photographed by Thambu and edited by B. Kanthasamy, and the dialogues were written by Aaroor Dass.

Deiva Magan was released on 5 September 1969; it received critical acclaim, primarily for Ganesan's performance, and was a commercial success, running for more than 100 days in theatres. It won the Tamil Nadu State Film Awards for Third Best Film and Best Actor (Ganesan), and was the first South Indian film to be submitted by India in contest for the Academy Award for Best Foreign Language Film.
