Chhoti Si Baat (translation: A Small Matter) is a 1975 Indian Hindi-language romantic comedy film directed by Basu Chatterjee. Considered one of the best Hindi comedy films of the 1970s, it is a nostalgic favourite for its quirky take on pre-hypercongestion Mumbai. The film became a box office hit and stars Amol Palekar, Vidya Sinha, Ashok Kumar and Asrani in lead roles. and also earned six Filmfare nominations and a Filmfare Award for Best Screenplay for Basu Chatterjee. The film is a remake of the 1960 British film School for Scoundrels.

It also established Amol Palekar as having an uncommon comic talent for playing mousy characters, a role he would go on to repeat several times in his career. As with other Basu Chatterjee films, movie stars have small cameos playing themselves: Dharmendra and Hema Malini (whose mother Jaya Chakravarthy helped produce the film) are in a movie-within-a-movie for the song Janneman Janneman, while Amitabh Bachchan plays himself in another scene, where he seeks advice from Ashok Kumar's character. He is dressed in costume from Zameer, whose film poster is prominently displayed at the bus stop scenes in Chhoti Si Baat. B.R. Chopra is the producer for Zameer, just as he is for Chhoti Si Baat.
