Chaudhvin Ka Chand (transl. The Full Moon) is a 1960 Indian Hindi-language film directed by Mohammed Sadiq.

This film was a super-hit at the box-office, and became one of the top-grossing films of 1960. A production of Guru Dutt, the film centers on a love triangle between Dutt, Rehman and Waheeda Rehman, and features music by Ravi. After the disastrous box office performance of Kaagaz Ke Phool, Guru Dutt ventured into the idea of producing a commercial project to protect his studio from ruin. The next commercial venture by the studio was Chaudhvin ka Chand, which was a successful comeback film for Guru Dutt and saved Guru Dutt's production studio.

The film is considered a notable Muslim-social. It was ranked #28 in 2003 Outlook Magazine poll of 25 Leading Indian Directors for "Best Bollywood Movies of all time". Filmfare listed it among "Seven Muslim socials you must watch".

Its music album was ranked #30 in Top 100 Bollywood Albums by Film Companion website. The film's title track "Chaudhvin Ka Chand" became especially popular and is noted for picturization of the song sequence. The song is regarded as one of the most acclaimed romantic ballads in India and one of the most loved filmi songs of all time.

In 2014, the film's screenplay was published as a book, titled Chaudhvin Ka Chand: The Original Screenplay, by the film historians Dinesh Raheja and Jitendra Kothari.

This film also entered into the 2nd Moscow International Film Festival.
