Aleksandr Vassilievich Gauk (Russian: Алекса́ндр Васи́льевич Га́ук; 15 August [O.S. 3 August] 1893 – 30 March 1963) was a Russian/Soviet conductor and composer.

Gauk’s first conducting experience was in 1912 with a student orchestra, and professionally on 1 October 1917 for a production of Tchaikovsky's Cherevichki at the Petrograd Musical Drama Theatre. He spent much of the 1920s as conductor for the Mariinsky Ballet. He married the ballerina Elena Gerdt.

From 1930 to 1934, he was chief conductor of the Leningrad Philharmonic Orchestra. On 6 November 1931, he conducted that orchestra and the Academy Capella Choir in the world premiere of Shostakovich's Symphony No. 3 in E flat major, Op. 20 "First of May".

From 1932 he worked in Moscow and became chief conductor of a new radio orchestra in 1936, which evolved into the USSR State Symphony Orchestra. During the Second World War, after escaping from Riga, he taught in Moscow, before spending two years at the Tbilisi Conservatory and reviving the Georgian State Symphony Orchestra.

He restored Rachmaninoff's discarded First Symphony from the orchestral parts found in the archives of the Moscow Conservatory after the composer's death in 1943. He conducted the world premiere of Khachaturian's Cello Concerto in Moscow in 1946.

Gauk's own compositions include a symphony, chamber works for strings and works for piano. He left an unfinished autobiography.
