The 2018 Alabama Senate elections took place on November 3, 2018, as part of the 2018 United States elections. Alabama voters elected state senators in all 35 of the state's Senate districts. State senators serve four-year terms in the Alabama Senate. A primary election on June 5, 2018, and a runoff election on July 17, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the Alabama Secretary of State's website. To claim control of the chamber from Republicans, the Democrats would have needed to gain 10 Senate seats.
