The 2020 Arkansas Senate elections took place as part of the biennial 2020 United States elections. Arkansas voters elected state senators to the Arkansas Senate in 17 of the state's 35 senate districts. The primary elections on March 3, 2020, determined which candidates would appear on the November 3, 2020, general election ballot.
The outcome of this election was identified by the National Conference of State Legislatures as one of many that could affect partisan balance during post-Census redistricting.[1]
Following the previous election in 2018, Republicans, led by Bart Hester (AR-01), had control of the Arkansas Senate with 26 seats to Democrats, led by Keith Ingram (AR-24), with nine seats. In the 2020 cycle, Republicans made a net gain of two seats, defeating two incumbent Democratic senators, bringing the partisan balance to a 28-7 supermajority.
