Irudhi Suttru (transl. Final round) is a 2016 Indian sports drama film written and directed by Sudha Kongara. Filmed simultaneously in Tamil and Hindi, with the latter being titled as Saala Khadoos (transl. Bloody Grouch), the film stars R. Madhavan as boxing coach who is ignored by the boxing association, tries to accomplish his dream by training an amateur boxer, Madhi, played by Ritika Singh in her acting debut. Both the Tamil and Hindi versions are produced by S. Sashikanth for YNOT Studios and UTV Motion Pictures, while C. V. Kumar's Thirukumaran Entertainment and Dream Factory distributed the Tamil version and the Hindi version was jointly distributed by Madhavan himself under the Tricolour Films banner along with Rajkumar Hirani Films.

Kongara wrote the script for the film in early 2011, and approached Madhavan for the leading role, for whom the film marks his comeback to Tamil cinema after four years. The pre-production works of the film began during 2013, and was officially announced by Sashikanth in May 2014. The film's shooting began in July 2014 and completed that December, with the entire film was shot within fifty days. Featuring music composed by Santhosh Narayanan, with a background score by Sanjay Wandrekar and Atul Raninga (for the Hindi version), the film has cinematography by Sivakumar Vijayan and editing by Sathish Suriya.

Both versions Irudhi Suttru and Saala Khadoos opened on 29 January 2016. Unlike the Hindi version which received mixed reviews, the Tamil version opened to critical acclaim, praising the performances of Madhavan and Singh, and the story, direction and other technical aspects. A commercial success at the box office, Irudhi Suttru won the National Award for Special Mention (Ritika Singh), six Tamil Nadu State Film Awards, three Filmfare Awards: Best Director (Kongara), Best Actor (Madhavan), Best Actress (Ritika Singh). In addition, the film won three awards each at the Ananda Vikatan Cinema Awards, IIFA Utsavam Awards and SIIMA Awards. The film was later remade by Kongara herself in Telugu language as Guru (2017) with several members of the cast reprising their respective roles and Venkatesh reprising Madhavan's role. It is also the last South Indian movie produced by UTV.
