John Thompson Hoffman (10 January 1828–24 March 1888) was born in Ossining in Westchester County, New York. He was governor of New York (1869 -1873). He was also a judge (elected 1860) and Mayor of New York City (1866 - 1868). Connections to the Tweed Ring ruined his political career, in spite of the absence of evidence to show personal involvement in corrupt activities.

Hoffman died in Germany.
