Anchakkallakokkan: Porattu (transl. Boogeyman) is a 2024 Indian Malayalam-language action drama film directed by Ullas Chemban (in his directorial debut), written by Chemban and Vikil Venu, and produced by Chemban Vinod Jose through Chembosky Motion Pictures. The film stars Lukman Avaran, Chemban Vinod Jose, and Manikandan R. Achari. The narrative follows the investigation of a landlord's homicide and the truths uncovered as events progress.

Development of Anchakkallakokkan began during the COVID-19 lockdown when a friend of Ullas Chemban shared an anecdote about a police officer. Collaborating with Vikil Venu, Ullas commenced scripting in 2022, which took 10 months to complete. Shortly after, pre-production work began. Principal photography took place between January 2023 and March 2023 and was primarily shot in Vandiperiyar and Kumily.

The film was released in theatres on 15 March 2024. In their year-end report, Kerala Film Chamber of Commerce classified Anchakkallakokkan as an "average hit".
