The 2018 Maine State Senate elections took place as part of the biennial United States elections. Maine voters elected state senators in all 35 of the state senate's districts. State senators serve two-year terms in the State Senate.
A primary election on June 12, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the Maine Secretary of State's website.
Following the 2016 state Senate elections, Republicans maintained effective control of the House with 18 members.
The Maine Secretary of State provides both a detailed description of each Senate seat as well as maps for each district, including this statewide Senate map showing all 35 Senate districts.
After the 2018 elections, Republicans lost control of the chamber. The Democrats needed to net one Senate seat. In the election, the Democrats gained four seats, claiming the majority.
