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.

Incidentally, both Bond and Ashcroft would later serve in the United States Senate from 1995 until 2001.
