Madhu Malathi () is a 1966 Indian Kannada-language romantic drama film directed by S. K. A. Chari and produced by M. Sampath. The film stars Rajkumar, Udaykumar, Arun Kumar and Bharathi Vishnuvardhan. The musical score was composed by G. K. Venkatesh.

The title card credits the story to the director, noting that it was based on a book by Bhavabhuti. The story traces its origins to the ancient Indian drama Mālatīmādhava by Bhavabhuti (c. 8th-century) and later became one of the popular Vikram - Vetal stories from Vetala Panchavimshati, a Sanskrit work whose earliest recensions are found in Kathasaritsagara written by Somadeva (c. 11th-century).

The film was dubbed as Vedhalan Sonna Kathai in Tamil . The film features characteristics of swashbuckler films with the three male leads playing swashbucklers and the sole female lead portraying a damsel in distress. This was the first film where Bharathi was paired with Rajkumar.
