Rajnigandha (transl. Tuberose) is a 1974 Hindi film directed by Basu Chatterjee. It is based on the short story "Yahi Sach Hai" by noted Hindi writer Mannu Bhandari. The movie starred Amol Palekar, Vidya Sinha and Dinesh Thakur in the lead.

Rajnigandha went on to win the Best Picture, the Popular Award and the Critics Award at the Filmfare Awards in 1975. It was considered to have a realistic outlook of urban middle class on cinema in 1974, an era when potboilers were ruling Bollywood, a genre which was later called the Middle Cinema. The film was the first screen role of Vidya Sinha and first Hindi film of Amol Palekar, both of whom went on to work with Basu Chatterjee in many films. Rajnigandha was remade into Bengali in 2012 as Hothat Shedin.
