The presidency of Benjamin Harrison began on March 4, 1889, when Benjamin Harrison was inaugurated as President of the United States, and ended on March 4, 1893. Harrison, a Republican, took office as the 23rd United States president after defeating Democratic incumbent President Grover Cleveland in the 1888 election. Four years later he was defeated for re-election by Cleveland in the 1892 presidential election. Harrison is the only president to be preceded and succeeded by the same individual.

A 2017 C-Span poll of historians ranked Harrison as the 30th best president. Historian Allan B. Spetter writes,
