The 2006 United States Senate election in Missouri was held November 7, 2006, to decide who would serve as senator for Missouri between January 3, 2007, and January 3, 2013. The incumbent was Republican Jim Talent. Talent was elected in a special election in 2002 when he narrowly defeated incumbent Democrat Jean Carnahan. Carnahan had been appointed to the Senate seat following the posthumous election of her husband Mel Carnahan, who had died in a plane crash shortly before the 2000 election. Talent's Democratic opponent was Missouri State Auditor Claire McCaskill. Early on the morning of November 8, Talent conceded defeat to McCaskill, having faced considerable political headwinds. Talent lost the election with 47% of the vote, to 50% of the vote for McCaskill. This was the last election an incumbent Republican senator lost in Missouri.

Mel Carnahan died in a plane crash before election day, so his wife Jean Carnahan was appointed to the seat after the election. Two years later in a special election held for the seat, incumbent Senator Jean Carnahan lost an even closer election to former Congressman Talent, 50% to 49%. State politics Missouri was seen as the nation's bellwether state throughout the 20th century. It had voted for the winner of every presidential election since 1900, except for 1956 (when the state narrowly favored Adlai Stevenson over Dwight D. Eisenhower). Missouri's bellwether status was due to the fact that it not only voted for the electoral victor, but that its returns usually mirrored national returns. The state itself is a geographically central state, bordered by both the edges of Southern and Midwestern regions. In statewide contests for much of the 20th century, Missouri favored the Democratic Party. In recent elections, the Republican Party (GOP) has emerged in statewide contests. The election of 2004 was an important one; as George W. Bush was re-elected he carried Missouri. But this time his
