The United States gubernatorial elections of 1984 were held on November 6, 1984 in thirteen states. The Republican party had a net gain of one seat in this election which coincided with the re-election of Ronald Reagan. This was the last year in which Arkansas held a gubernatorial election on the same year as the presidential election. The length of gubernatorial terms for Arkansas' governor would be extended from two-years to four years with elections taking place in Midterm election years following the passage of the Sixty-third Amendment to the Arkansas Constitution.
