2018 Alabama Senate election

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.

Following the 2014 state Senate elections, Republicans maintained effective control of the House with a 27-seat majority—26 Republican members and 1 independent who caucuses with the Republicans. Democrats hold 8 seats following the 2014 elections.

To claim control of the chamber from Republicans, the Democrats would have needed to gain 10 Senate seats.

The election resulted in the Republican Party holding all previously held seats and taking a seat previously held by an independent who caucused with the Republicans, leading to no effective shift in control of the chamber. The Republicans also gained slightly in the popular vote compared to the 2014 elections.
