The 1916 United States presidential election in Illinois was held on November 7, 1916 as part of the 1916 United States presidential election. State voters chose 29 electors to the Electoral College, who voted for president and vice president. Illinois was won by the Republican nominee Charles Evans Hughes with 52.56% of the popular vote. Hughes was the first presidential candidate to garner over a million votes in a single state, due to Illinois having allowed women to cast votes for electors, though not yet for other offices.
