Aalavandhan (transl. He Came to Rule) is a 2001 Indian action thriller film directed by Suresh Krissna and produced by Kalaipuli S. Thanu. The film features Kamal Haasan in dual roles, alongside Raveena Tandon, Manisha Koirala, Sarath Babu, Gollapudi Maruti Rao, Madurai G.S. Mani. and Milind Gunaji. It is an adaptation of the 1984 novel Dhayam, written by Haasan, and incorporates elements of magical realism. The film was simultaneously shot in Tamil and Hindi, with the latter version titled Abhay (transl. Fearless), with three different actors in supporting roles. The Tamil version was dubbed into Telugu and released under the title Abhay.

While Aalavandhan underperformed commercially upon its release, it was positively received in subsequent years and achieved cult status, with some critics praising it as being ahead of its time. The film won the National Film Award for Best Special Effects and was retrospectively screened at the 2016 Fantastic Fest, where it received a standing ovation. In 2013, it was included in Rediff's list of "The 10 Best Films of Kamal Haasan." A digitally remastered version, heavily trimmed by 50-55 minutes, was released on 8 December 2023.
