George J. Zimmermann (June 19, 1882 – September 14, 1938) was Mayor of the City of Buffalo, New York, serving from 1934 until 1937.

[2] During the mayoral campaign, Zimmermann travelled to New York City and Washington, D.C. and secured almost $6,000,000 worth of construction to be financed with federal funds for the Fillmore-Lovejoy sewer project and Kensington High School.

Included were Zimmermann's part in the sewage disposal project and the reported "deal" with former Mayor Schwab.

He was once again indicted on March 14, 1938, by a grand jury related to his alleged activity regarding Buffalo's $15,000,000 sewer project.

A New York Supreme Court jury returned guilty verdicts on six of the nine counts charged against him.
