Khamoshi (transl. Silence) is a 1970 black-and-white Hindi drama film directed by Asit Sen, starring Waheeda Rehman and Rajesh Khanna. It is especially remembered for its memorable music by Hemant Kumar and lyrics by Gulzar in songs such as "Tum Pukaar Lo... Tumhara Intezaar Hai" sung by Hemant Kumar, "Woh Shaam Kuch Ajeeb Thi" by Kishore Kumar and "Humne Dekhi Hai In Aankhon Ki Mehekti Khushboo" sung by Lata Mangeshkar. Though what really made this film stand out was the B&W cinematography by Kamal Bose, who won Best Cinematographer at the 18th Filmfare Awards for his work in the film and received high critical acclaim for Rehman and Khanna's performances. Rehman's performance earned her a Best Actress nomination at the same ceremony. The film was a moderate success at the box-office.

Khamoshi was shot in Calcutta and was based on the Bengali short story titled Nurse Mitra by noted Bengali writer, Ashutosh Mukherjee and is a remake of director Asit Sen's own Bengali film, Deep Jwele Jaai (1959), starring Suchitra Sen. The Bengali original proved to be a hit at the box office, especially at the urban centres. Impressed by the story line, producer Vuppunuthula Purushotham Reddy and director G. Ramineedu remade the Bengali film into Chivaraku Migiledi (1960), which was a blockbuster.
