Raman Raghav 2.0 (released internationally as Psycho Raman) is a 2016 Indian neo-noir psychological thriller film directed by Anurag Kashyap. Produced by Kashyap, Vikramaditya Motwane, Vikas Bahl, and Madhu Mantena, the film stars Nawazuddin Siddiqui, Vicky Kaushal, and debutante Sobhita Dhulipala. It depicts in eight chapters the cat and mouse chase of serial killer Ramanna (Siddiqui) by corrupt cop Raghavan (Kaushal). Real-life killer Raman Raghav, who operated in Mumbai during the 1960s, inspired the film.

Kashyap initially wanted to make a period film about Raman Raghav, but after the commercial failure of Bombay Velvet (2015), his previous film that was also set in the 1960s, he realized that he would be unable to find financing. Abandoning the period-piece concept, he co-wrote the film with Vasan Bala, setting it in the contemporary time. The film's music was composed by Ram Sampath, and Varun Grover wrote the lyrics. Jay Oza served as the film's cinematographer and Aarti Bajaj as its editor.

Raman Raghav 2.0 premiered in the Directors' Fortnight section at the 2016 Cannes Film Festival. It also screened at the 2016 Sydney Film Festival, the Singapore International Film Festival, the Fantasia International Film Festival, Bucheon International Fantastic Film Festival, and the Indian Film Festival of Melbourne. The film was released in India on 24 June 2016, received high critical acclaim, and proved to be a moderate commercial success, grossing over ₹70 million (US$1.1 million).
