Chalti Ka Naam Gaadi (transl. That which moves is called a car) is a 1 January 1958 Indian musical comedy film directed by Satyen Bose. Starring Madhubala with the Ganguly brothers —Ashok Kumar, Anoop Kumar, and Kishore Kumar— the film revolves around a middle-aged man who resents women due to some misunderstandings and forbids his younger brothers from marrying.

Expected by Kishore Kumar to flop, Chalti Ka Naam Gaadi opened to major commercial success, eventually becoming the most successful work of Bose and Ganguly brothers, as well as Madhubala's fourth consecutive major hit of 1958, thus solidifying her position as the top female star of the late 1950s and early 1960s.

Chalti Ka Naam Gaadi has received overwhelmingly positive reviews from critics for its comical situations, soundtrack, execution, and performances. Over the years, the film has gained classic status and has also inspired several films including Badhti Ka Naam Dadhi (1974), Saade Maade Teen (2006) and Dilwale (2015). It was ranked #18 in 2003 Outlook Magazine poll of 25 leading Indian Directors for “Best Bollywood Movies of all time”.
