Edwin Joseph O'Malley (August 22, 1881 – April 10, 1953) was the Commissioner of Public Markets for New York City.

He married Alma Feltner (1883–1940) on January 16, 1902, and had one child, a son, Walter Francis O'Malley (1903–1979), who would become the owner of the Brooklyn Dodgers from 1950 to 1979, and who would oversee their controversial move from Brooklyn to Los Angeles.

In 1910, O'Malley was living in the Bronx, New York, and working as a cotton goods salesman.

He became a Democratic party ward heeler for Tammany Hall, and was appointed as the Commissioner of Public Markets for New York City by mayor John F. Hylan.

He testified on August 18, 1922, before the Kings County, New York Grand Jury, which was investigating the mishandling of the fees paid by vendors to the Public Markets office.
