2018 Georgia State Senate election

The 2018 Georgia State Senate elections took place as part of the biennial United States elections. Georgia voters elected state senators in all 56 of the state senate's districts. State senators serve two-year terms in the Georgia State Senate.

A primary election on May 22, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the Georgia Secretary of State's website.

Following the 2016 state senate elections, Republicans maintained effective control of the Senate with 38 members. However, on December 5, 2017 Democrats flipped State Senate district 6 after Democrat Jen Jordan won a special election. This decreased Republican seats from 38 to 37 and increased Democratic seats from 18 to 19.

To reclaim control of the chamber from Republicans, the Democrats would need to net 9 Senate seats and win the concurrent lieutenant gubernatorial election or net 10 seats without the Lieutenant Governor's office. Democrats flipped two seats—districts 40 and 48—from Republican control; however, Republicans retained control of the Georgia State Senate following the 2018 general election.
