Arkansas elections, 2010

Arkansas's 2010 general elections were held November 2, 2010. Primaries were held May 18, 2010 and runoffs, if necessary, were held November 23, 2010. Arkansas elected seven constitutional officers, 17 of 35 state senate seats, all 100 house seats and 28 district prosecuting attorneys, and voted on one constitutional amendment and one referred question. Non-partisan judicial elections were held the same day as the party primaries for four Supreme Court justices, four appeals circuit court judges, and eight district court judges.

Incumbent Democratic U.S. Senator Blanche Lincoln ran unsuccessfully for re-election against Republican John Boozman. Arkansas had previously only elected one Republican senator since the Reconstruction, 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 Democratic primary was held on May 18, 2010, with early voting from May 3–17. As no candidate received 50 percent of the vote, a runoff election was held on June 8, with early voting from June 1–7.

The Republican primary was held on May 18, 2010, with early voting from May 3–17.

All four of Arkansas's seats in the United States House of Representatives were up for election in 2010. Only one of the four incumbents sought re-election, Democrat Mike Ross of District 4.
