Nayak: The Real Hero (transl. Hero) is a 2001 Indian Hindi-language political action film directed by S. Shankar and produced by A. M. Rathnam under the Sri Surya Movies banner. The film stars Anil Kapoor, with Rani Mukerji, Amrish Puri, Paresh Rawal, and Johnny Lever playing supporting roles. A remake of Shankar's 1999 Tamil-language film Mudhalvan, it focuses on Shivaji Rao Gaekwad (Kapoor), a television cameraman and, later, television presenter, who accidentally hears and records the conversation between the police with the Chief Minister of Maharashtra Balraj Chauhan (Puri) to take an indifferent stand during riots triggered by a fight between college students and a bus driver. While interviewing Chauhan about the issues, Shivaji is challenged to take over his job for a day.

Nayak was announced in June 2000 and marked the first Hindi-language directorial venture of Shankar. The soundtrack was composed by A. R. Rahman, with lyrics that were written by Anand Bakshi. Filming was done by K. V. Anand, taking place in more than 100 locations across India. The film was released on 7 September 2001. A commercial failure, it grossed ₹205.6 million (US$2.6 million) at the box office against the total production and marketing cost of ₹210 million (US$2.6 million). It was opened to mixed reviews from critics, some of whom applauded the storyline, the performances (particularly Kapoor, Puri and Rawal), Shankar's direction and the movie's themes and social message but criticised its lengthy duration, editing, pace and special effects. Through repeated television airings, Nayak has since become a cult classic.
