Valmiki is a 1946 Indian Tamil-language film starring Honnappa Bhagavathar, U. R. Jeevarathinam, N. C. Vasanthakokilam, T. R. Rajakumari and T. S. Balaiah. It was directed by Sundar Rao Nadkarni.
The film is based on the story of the Hindu sage Valmiki, who starts as a bandit and eventually undergoes spiritual transformation into a religious mendicant. Valmiki falls in love with a princess, who is kidnapped by the villain (played by T. S. Balaiah).
The film began production in 1944 with M. K. Thyagaraja Bhagavathar as the lead actor. Mid-way through production, he was arrested in connection with the Lakshmikanthan murder case and with uncertainty over his release, the producers replaced him with Honnappa Bhagavathar; Thyagaraja Bhagavathar's scenes had to be re-shot.
The music was composed by S. V. Venkatraman and the lyrics were penned by Papanasam Sivan.
Valmiki was released on 13 April 1946. According to historian Randor Guy, the film was a "reasonable success".
