Devadoothan (transl. The Heavenly Messenger) is a 2000 Indian Malayalam-language musical horror film directed by Sibi Malayil, written by Raghunath Paleri, and produced by Siyad Koker through Kokers Films. It stars Mohanlal in the title role with Jaya Prada, Vineeth Kumar, Janardhanan, Jagathy Sreekumar, Murali, Jagadish, Sarath Das and Vijayalakshmi in supporting roles. The film features original songs and score composed by Vidyasagar. The cinematography was done by Santosh Thundiyil.

The plot follows an award winning musician Vishal Krishnamoorthy who returns to his alma mater to direct a musical. Years ago, he was expelled from the college by Madam Angelina Ignatius for allegedly playing a protected musical instrument, Seven Bells, which he claimed played by itself. Vishal encounters the same haunting melody and embarks on a quest to solve the mystery of the Seven Bells.

Devadoothan was released on 22 December 2000, during the Christmas season. Though the songs and performances were applauded, the film didn’t resonate much with the audience, citing it "The film was ahead of its times". Despite underperforming at the box office, the film received critical acclaim. Over the years, it has achieved a cult following. It won three Kerala State Film Awards, including Best Film with Popular Appeal and Aesthetic Value, Best Music Director, and Best Costume Designer. A digitally remastered 4K Dolby Atmos Director's Cut was released on 26 July 2024. The film became a commercial success after the re-release.
