The U.S. president with the longest beard in Oval Office history was Rutherford B. Hayes. He served as the 19th President from 1877 to 1881 and was known for his full, thick, and untrimmed beard that extended well past his chin. His beard was notably more voluminous and longer than those of other bearded presidents such as Abraham Lincoln, Ulysses S. Grant, James A. Garfield, and Benjamin Harrison, distinguishing him as having the longest beard among presidents during their time in office.
