Varalaru: History Of Godfather, or simply known as Varalaru (transl. History), is a 2006 Indian Tamil-language action-drama film written and directed by K. S. Ravikumar, and produced by S. S. Chakravarthy under the banner NIC Arts. The film stars Ajith Kumar in the main triple lead role as a father and his two twin sons. Asin, Kanika, Ramesh Khanna, Suman Setty, Sujatha and M. S. Baskar play supporting roles. The film's soundtrack and background score were composed by A. R. Rahman. The film ran for 215 days and became a blockbuster at the box office. Prior to its release, the film was known by the title Godfather, but following the Government of Tamil Nadu's motion to exempt tax on films titled in Tamil, the title was changed to Varalaru.

After two years of production, the film was released on 20 October 2006 on the eve of Diwali, and emerged as the highest grosser of the year. The film has been remade in Kannada, titled Godfather, in Burmese as Nat Khat Mhar Tae Tite Pwal, and in Odia as Tu Mo Dehara Chhai.
