Kati Patang (transl. The Severed Kite) is a 1971 Indian Hindi-language musical drama film produced and directed by Shakti Samanta. The film stars Asha Parekh as a woman pretending to be a widow, and her ensuing trials and tribulations opposite her charming neighbour, played by Rajesh Khanna. It was a box office success and Parekh's performance as Madhavi was critically acclaimed and earned her the Filmfare Award for Best Actress. The film also stars Nazir Hussain, Bindu, Prem Chopra, Daisy Irani and Sulochana Latkar.

It was the second in a string of nine films on which Samanta and Khanna collaborated. The music was composed by R.D. Burman and was a huge hit. "Ye Shaam Mastani" and "Pyaar Deewana Hota Hai", sung by Kishore Kumar were particularly famous. The performances from Parekh and Khanna were praised by the audience and critics alike. It was among the 17 consecutive hits of Khanna between 1969 and 1971 and was the second of four films in which he was paired with Parekh.

The film was later remade in Tamil as Nenjil Oru Mul (1981) and in Telugu as Punnami Chandrudu (1987). It is based on Gulshan Nanda's novel of the same name which was an adaptation of Cornell Woolrich's 1948 novel I Married a Dead Man which had earlier been adapted as the 1950 film No Man of Her Own.
