Rubik Mansuri (1937, Tehran - 21 August 2000, Tehran) was an Iranian-Armenian film composer, music arranger, editor and sound designer. His fame was mostly related to the field of film music and sound.

Rubik (Ali) Mansuri studied at the Music Academy and his specialized instrument was the flute, but when he entered the cinema industry, despite the fact that his name was registered as a producer or selector of the soundtrack, he did not follow his specialized field.

In 1956, at the suggestion of Hassan Musaibi, and as his assistant, Mansuri went to Borna Studio (Cinema Ten) which was managed by an American named Stephen Nyman, and undertook the task of sound designing for the dubbing of Shaitan-e Farari (under the dubbing guidance of Zia Al-Absaari).

The first film with Mansuri's name in its title is Storm in Our Town. In this film, he was the assistant of Sorik Khachikian and Henrik Avdisian and responsible for the sound of the film, and in Ghased-e Behesht (1959), Khachikian's next film, he was promoted to the position of sound designer alongside Sorik and Hakop Giorgiz.

Since then, Rubik Mansuri's name has been recorded in hundreds of films as a sound designer, mixer, effect, synchronist, choice of soundtrack, etc., and his activity continued until the last moments of his life on August 21, 2000, at the age of 62.

After Azhirfilm, Mansuri expanded his career in Iran Film, Pars Film, Misaghieh Studio, Shahin Film and Filmkar studios, and worked as sound designer for films such as The Midnight Terror (Samuel Khachikian 1961), Mr. Twentieth Century (Siamak Yasami 1964) and The Mummy (Hamid Mojtahedi 1966).
