John Baker Manning (July 13, 1833 – April 28, 1908) was Mayor of the City of Buffalo, New York, serving during January 1883 – 1884, in the aftermath of the resignation of Grover Cleveland.

He continued the string of vetoes begun by Mayor Grover Cleveland; they saved the city a great financial loss.

[5] He continued to grow and expand the malting business and built several grain elevators in the 1890s, each with a large storage capacity.

On May 30, 1902, the largest fire Black Rock had ever seen consumed Manning's Frontier Canada plant.

[4] He died on April 28, 1908, at 953 St. Mark's Avenue, his home in Brooklyn, New York,[6] and is buried in Forest Lawn Cemetery.
