Kalathur Kannamma is a 1960 Indian Tamil-language romantic drama film directed by A. Bhimsingh and written by Javar Seetharaman. The film stars Gemini Ganesh, Savitri Ganesh and Kamal Haasan. It revolves around a couple — a wealthy zamindar's son and a farmer's daughter — who are separated due to circumstances, while their innocent son is forced to grow up in an orphanage.

Kalathur Kannamma, inspired by the 1960 Chinese film Nobody's Child, was originally directed by T. Prakash Rao who left due to creative differences, resulting in Bhimsingh taking over. It was the debut film of Kamal Haasan. The film's soundtrack was composed by R. Sudarsanam.

Kalathur Kannamma was released on 12 August 1960. The film was critically acclaimed, with Haasan's performance being singled out. It was also commercially successful, running for over 100 days in theatres. It won the Certificate of Merit by the Government of India, and the President's Gold Medal award for Haasan at the age of 6. The film was remade in Telugu as Mooga Nomu, in Hindi as Main Chup Rahungi (with Bhimsingh returning as director), and in Sinhala as Mangalika.
