The 2010 United States Senate election in Arkansas took place on November 2, 2010, alongside other elections to the United States Senate in other states, as well as elections to the United States House of Representatives and various state and local elections.

This was one of the three Democratic-held Senate seats up for election in a state that John McCain won in the 2008 presidential election along with North Dakota and West Virginia. Incumbent Democratic Senator Blanche Lincoln ran for re-election to a third term, facing a strong primary challenge from Lieutenant Governor Bill Halter and prevailing only in a runoff. Lincoln then lost the general election to U.S. Representative John Boozman, the younger brother of Fay Boozman, whom Lincoln defeated in 1998. Boozman became the first Republican since Reconstruction in 1872 to win this seat. Lincoln's 21% margin of defeat was the largest for a sitting senator since the 1978 United States Senate election in Maine. With Democratic Governor Mike Beebe concurrently winning re-election, this is the last time that Arkansas simultaneously voted for gubernatorial and U.S. Senate candidates of different political parties.

Democratic primary The Democratic primary was held on May 18, 2010, with early voting from May 3 to 17. Lincoln was challenged by Lieutenant Governor Bill Halter, who ran as a more liberal alternative. As no candidate received 50 percent of the vote, a runoff election was held on June 8, with early voting from June 1 to 7. Lincoln managed to narrowly defeat Halter in the runoff.

MoveOn.org supported Halter, criticizing Lincoln for her stance on issues such as health care and environmental regulations.Cillizza, Chris. "The Fix" Washington Post, March 3, 2010. Labor unions also backed Halter, and pledged to spend more than $3 million on his campaign.DeMillo, Andrew. "Halter raises more than $2M for Ark. Senate bid" Business Week, April 1, 2010.

General election

Candidates John Boozman, U.S. representative Trevor Drown (L), military veteran John Gray (G), mayor of Greenland Blanche Lincoln, incumbent senator

Campaign Arkansas had previously only elected one Republican senator since the Reconstruction, Tim Hutchinson who was defeated after his first term in 2002 by Mark Pryor. Lincoln faced Lieutenant Governor Bill Halter and narrowly won the primary contest.

The political blog FiveThirtyEight ranked Lincoln the most vulnerable senator of this electoral cycle. RealClearPolitics claimed that in 2010 Lincoln had the potential for the lowest percentage of the vote for any incumbent since the nation first began directly electing senators. Boozman received 58% of the vote in the general election and defeated Lincoln (37%), Independent Trevor Drown (3%) and Green John Gray (2%).

Lincoln heavily criticized Boozman for supporting the FairTax and privatization of Social Security, as well as for trying to tie her name, and beliefs to Bill Clinton. She released an advertisement touting her support for earmarks.
