The 2008 Missouri gubernatorial election was held on November 4, 2008. Incumbent Republican Governor Matt Blunt decided to retire instead of seeking reelection to a second term in office. Democratic nominee Jay Nixon won the open seat, defeating Republican nominee Kenny Hulshof.
On January 22, 2008, Governor Blunt unexpectedly announced that he would not seek re-election  because he had already "achieved virtually everything I set out to accomplish, and more ... Because I feel we have changed what I wanted to change in the first term, there is not the same sense of mission for a second."

On election night, Nixon won easily, even though fellow Democrat, then-senator Barack Obama came within only 4,000 some votes of winning the state. Nixon was able to perform well in rural parts of the state. When combined with heavily populated, strong Democratic areas like St. Louis and Kansas City, Hulshof didn't have a chance to come back. Nixon was declared the winner right when the polls closed in Missouri. Hulshof conceded defeat at 9:02 P.M. Central Time.
