Elections of New York City's borough presidents were held on November 5, 1929, in concert with such contests as the mayoralty, Comptroller, aldermen, County Sheriffs, Aldermanic Board President, and other miscellaneous questions on the ballot. Democrats were elected in all Boroughs except Queens. This and Democratic victories in other contests were all a part of what was considered "a Crushing Defeat to [the] City G.O.P. [delivered]" by Tammany Hall.
Democratic incumbent Julius Miller defeated Republican challenger Fay.
