Phool Aur Patthar (transl.  The Flower and The Rock) is a 1966 Indian Hindi-language romantic drama film directed and produced by O. P. Ralhan, and written by Ralhan with Akhtar ul Iman and Ahsan Rizvi. It stars Meena Kumari and Dharmendra as contrasting characters who come together; he plays a tough criminal (the "Stone") whose inner good being (the "Flower") is drawn out by Kumari's character of a pure woman. The film made Dharmendra a star in Hindi cinema. It also stars Shashikala, Lalita Pawar, Madan Puri, and Iftekhar.

The film later became a golden jubilee hit, catapulting Dharmendra to stardom. It was the highest-grossing film in 1966. Due to Dharmendra's rugged physique, he was also acknowledged as the He-man of the Indian film Industry. In fact, a scene in the film where he takes off his shirt to cover the ailing Leela Chitnis was one of the highlights of the movie. His performance earned him a nomination in the Best Actor category at the Filmfare Awards that year. In the 1960s, it was unusual for the leading man not to sing any songs in a movie. The film was noted for making Dharmendra-Meena Kumari a popular couple and they later acted in other movies such as Chandan Ka Palna, Majhli Didi, and Baharon Ki Manzil.

During shooting at one point, Dharmendra had a show-down with the film's director O. P. Ralhan, since he felt that the director had an arrogant attitude and he contemplated quitting the film mid-way. However, better sense prevailed and he resumed shooting.

The film was remade in Tamil as Oli Vilakku with M. G. Ramachandran, in Telugu as Nindu Manasulu with N. T. Ramarao, and in Malayalam as Puthiya Velicham with Jayan.
