Kalai Kovil (transl. Temple of art) is a 1964 Indian Tamil-language musical film written and directed by C. V. Sridhar. The film stars S. V. Subbaiah, R. Muthuraman, Chandrakantha and Rajasree, with Nagesh, V. Gopalakrishnan, V. S. Raghavan, Jayanthi and S. N. Lakshmi in supporting roles. It focuses on the rags to riches story of a veena vidwan, whose success is almost derailed when he takes to liquor abuse.

Kalai Kovil was produced under the banner Bhagyalakshmi Productions by M. S. Viswanathan (using the name Visu) and Ganga. Viswanathan also composed the film's soundtrack with T. K. Ramamoorthy under the name Viswanathan–Ramamoorthy, and Ganga also served as the art director. Sridhar's frequent collaborator Chitralaya Gopu served as the film's assistant dialogue writer.

Kalai Kovil was released on 25 September 1964 and received positive reviews from critics for its music, cast performances, writing and direction by Sridhar. It was not commercially successful, but the song "Thangaratham Vanthathu", performed by P. Susheela and M. Balamuralikrishna, attained popularity.
