Charles Julius Guiteau was an American man who assassinated James A. Garfield, president of the United States, in 1881. Guiteau falsely believed he had played a major role in Garfield's election victory, for which he should have been rewarded with a consulship. He felt frustrated and offended by the Garfield administration's rejections of his applications to serve in Vienna or Paris to such a degree that he decided to kill Garfield and shot him at the Baltimore and Potomac Railroad Station in Washington, D.C. Garfield died two months later from infections related to the wounds. In January 1882, Guiteau was sentenced to death for the crime and was hanged five months later.

The 1880 United States presidential election was the 24th quadrennial presidential election, held on Tuesday, November 2, 1880, in which Republican nominee James A. Garfield defeated Winfield Scott Hancock of the Democratic Party. The voter turnout rate was one of the highest in the nation's history. Garfield was assassinated during his first year in office, and he was succeeded by his vice president, Chester A. Arthur.
