Nagina is a 1986 Indian fantasy romance film, produced and directed by Harmesh Malhotra, with a screenplay written by Ravi Kapoor and story by Jagmohan Kapoor. The film stars Sridevi as Rajni, a Nāginī who marries a civilian to avenge the death of her spouse at the hands of an evil saint. It also stars Rishi Kapoor, Komal Mahuvakar, Amrish Puri, Sushma Seth and Prem Chopra. Then dubbed in Telugu as Naagini.

Nagina was theatrically released on 28 November 1986. Upon its release, it was a widespread success grossing over ₹13 crore at the box office, becoming the second-highest-grossing Indian film of 1986. The success of the film proved to be one of the biggest blockbusters of the year. And major watershed moment in Indian cinema, as the film, despite being a woman-centric movie became a massive commercial success. Nagina is credited as being the film which established Sridevi's position as the biggest female star of the 1980s, rivaling male stars like Amitabh Bachchan and Dharmendra. A sequel to the film was released; Nigahen: Nagina Part II (1989), but failed commercially. Today, Nagina is considered one of Sridevi's finest performances.
