Jaani Dushman: Ek Anokhi Kahaani (transl. Sworn Enemy: A Unique Story) is a 2002 Indian Hindi-language fantasy action thriller film directed and produced by Rajkumar Kohli, making it his last film as a director. The film features an ensemble cast; including Sunny Deol, Akshay Kumar, Sonu Nigam, Suniel Shetty, Aftab Shivdasani, Arshad Warsi, Aditya Pancholi, Rambha and Sharad Kapoor, Manisha Koirala and Armaan Kohli.

The film was Armaan Kohli's comeback film where he was reintroduced with a new name Munish Kohli. Before its release, the film generated considerable hype for its innovative special effects, uncommon in the industry at the time. It also marked the first film featuring both Akshay Kumar and Sunny Deol, two major action stars of the previous decade, though they had no scenes together.

Upon its release, the film received overwhelmingly negative reviews and was a box office failure. Critics cited a poorly executed story, illogical scenes, and miscasting, notably the use of older actors as college students. Several scenes were plagiarised from Hollywood films, including The Terminator and The Matrix. The film is widely regarded as one of the worst ever made. Following its failure, director Rajkummar Kohli retired from filmmaking. Singer Sonu Nigam, who debuted as an actor in the film, was poorly received. The careers of actresses Rambha, Kiran Rathod, Pinky Campbell, and actor Siddharth Ray also ended with this film.

Over the years, Jaani Dushman achieved cult status in the "so bad it's good" genre due to frequent television re-runs.
