United States gubernatorial elections were held on November 6, 1984, in 13 states and two territories. The Republicans had a net gain of one seat in this election, which coincided with the Senate, House elections and presidential election.
This was the last year in which Arkansas held a gubernatorial election in 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.

Missouri
The 1984 Missouri gubernatorial election was held on November 6, 1984 and resulted in a victory for the Republican nominee, Missouri Attorney General John Ashcroft, over the Democratic candidate, Lt. Governor Ken Rothman, and Independent Bob Allen. Incumbent Republican Governor Kit Bond, who was elected to the Governorship in 1972, but lost re-election in 1976 before regaining the office in 1980, chose not to seek a third non-consecutive term.
Montana
The 1984 Montana gubernatorial election took place on November 6, 1984. Incumbent Governor of Montana Ted Schwinden, who was first elected in 1980, ran for re-election. Schwinden won the Democratic primary against a perennial candidate, and moved on to the general election, where he faced Pat M. Goodover, a State Senator and the Republican nominee. Although then-President Ronald Reagan won the state in a landslide that year in the presidential election, Schwinden defeated Goodover with over 70% of the vote to win his second and final term as governor.
New Hampshire

North Carolina
The 1984 North Carolina gubernatorial election was held on November 6, 1984. Democratic incumbent Jim Hunt was unable to run for another consecutive term under the North Carolina Constitution. Hunt ran instead for the U.S. Senate against Jesse Helms and lost, although he later announced his campaign for a third gubernatorial term in the 1992 election. Popular 9th District Congressman James G. Martin ran as the Republican nominee against Democratic Attorney General Rufus L. Edmisten, who defeated Hunt's Lt. Governor, James Green, among other candidates, in a hotly contested primary.
Martin won by a comfortable margin on Election Day thanks to the surprise endorsement of Green, and to President Ronald Reagan's coattails (see also 1984 United States presidential election). Martin became just the second Republican elected to the state's highest office in the 20th century.
