Isaac Iosifovich Schwartz (Russian: Исаак Иосифович Шварц; 13 May 1923 – 27 December 2009), also known as Isaak Shvarts, was a Soviet composer.

Schwartz's father was professor of archeology at the Leningrad State University: he was arrested in 1936 and executed two years later as part of the Great Purge.

[3] Shostakovich helped Schwartz gain entry to the Rimsky-Korsakov Conservatory in Leningrad, whence he graduated with a diploma in composition in 1951.

He went on to compose the music for more than 100 Soviet films, including White Sun of the Desert (Белое солнце пустыни, 1969) and The Captivating Star of Happiness (Звезда пленительного счастья, 1975).

He won the prestigious Nika Award of the Russian Academy of Cinema Arts and Sciences for 1992 for his music for the films White King, Red Queen (Белый король, красная королева) and Luna Park (Луна-парк).
