Bombai Ka Babu (transl. Gentleman from Bombay) is a 1960 Hindi film directed by Raj Khosla and written by Rajinder Singh Bedi. The film stars Dev Anand and Suchitra Sen in a rare appearance in Hindi cinema.

Except for the "brother-sister" angle, the plot of Bombai Ka Babu is inspired by O. Henry's short story, "A Double-Dyed Deceiver". The 1974 movie Zameer starring Amitabh Bachchan and Saira Banu was also based on the same story.

With classic songs such as "Chal Ri Sajni, Ab Kya Soche", by Mukesh, and "Deewana Mastana Hua Dil" by Mohd. Rafi and Asha Bhosle, the film was a musical masterpiece, with music by S. D. Burman and lyrics by Majrooh Sultanpuri. Raj Khosla was also the director of Dev Anand's suspense thrillers like C.I.D. (1956) and Kala Pani (1958).

Initially, Madhubala was the choice for playing the female lead, but she had to withdraw owing to her poor heart condition.
