Arthur Oscar Bergh (March 24, 1882 – February 11, 1962) was an American composer, conductor and accompanist. He performed on the piano, violin and organ.

Bergh was born in Saint Paul, Minnesota. From 1903 to 1908 he was a violinist with the Metropolitan Opera. In 1914, he was the conductor of the orchestra in New York City's Central Park. Bergh became the recording manager at Emerson Records in 1916; he had previously been employed by Columbia Records, and was convinced to move to Victor Emerson's new company after Emerson himself left Columbia. Other sources state that Bergh worked with Emerson first (1915 to 1922), following which he worked at Columbia (1922 to 1930).

In his later life, Bergh worked as a librarian with Hollywood film companies. He died in Los Angeles on February 11, 1962.

Bergh's wife, Geraldyne Brewer (1901–1998), was an heiress in social and charitable circles in 1950s Los Angeles. In 1956, they lived at 9823 Kincardine Avenue in Cheviot Hills, Los Angeles. After Bergh's death, Geraldyne married Los Angeles Superior Court judge McIntyre Faries on December 3, 1965. Geraldyne died in 1998 and was buried in Forest Lawn Memorial Park, Glendale.
