Josiah Zuro (27 November 1887, in Białystok – October 18, 1930, in La Jolla, California) was a Russian-American pianist, conductor and film composer.

His idea of giving the concerts on Sunday was to provide a closer tie between music and religion, and each performance was accompanied by a speech by some person prominent in public life, usually a minister.

In 1924 John Haynes Holmes characterized the Sunday performances as a "ministry of music", adding that "this service, religious in character, rises to a plane of dignity and beauty which makes musicians priests of the loveliest of arts.

Zuro died in an ambulance on the way to Scripps Memorial Hospital at La Jolla, California, on Saturday night, October 18, 1930, having been injured when the car he was driving left the highway and overturned on Torrey Pines Road north of San Diego.

Funeral services for Zuro were held at the Glasband & Groman Mortuary in Los Angeles; the body was taken to New York for burial by train the following day.
