Chandni (Moonlight) is a 1989 Indian Hindi-language romantic musical drama film directed and co-produced by Yash Chopra from a story written by Kamna Chandra with a screenplay by Umesh Kalbagh, Arun Kaul, and Sagar Sarhadi.

The eighties marked a professional setback in Chopra's career, After a series of failed action films, Chopra decided to return to his roots and make a romantic musical, a film with all the hallmarks of what has come to be known as the "Yash Chopra style" – heroine-oriented, romantic, emotional, depicting the lifestyle of the super-elite, with melodic music used in songs picturized in foreign locations. The film marked the first collaboration between Chopra and Sridevi; they would collaborate again for the path-breaking Lamhe (1991).

Chandni was theatrically released on 14 September 1989 by Yash Raj Films. The film emerged as a widespread critical and commercial success, ranking as the third highest-grossing Hindi film of the year, with its soundtrack emerging as the best-selling album of the year as well as the decade, with more than 10 million copies sold. The massive success of the film and its soundtrack were instrumental in ending the era of violent action films in Indian Cinema and rejuvenating the romantic musical genre. The success of film further reinforced Sridevi's position as the top female star of the era. Over the years, Chandni is hailed as one of Chopra's finest films.
