2018 Vermont Senate election

The 2018 Vermont Senate election took place as part of the biennial United States elections. Vermont voters elected State Senators in all 30 seats. State senators serve two-year terms in the Vermont Senate. A primary election on August 14, 2018, determined which candidates appeared on the November 6 general election ballot.

Following the 2016 State Senate elections, Democrats maintained effective control of the Senate with 23 members in the majority caucus (21 Democrats and 2 Progressives). To claim control of the chamber from Democrats, the Republicans would have needed to net gain 8 or 9 seats depending on the winner of the 2018 Vermont Lieutenant Governor election, which was Progressive Dave Zuckerman. However, in the elections, the Democrats instead gained one seat from the Republicans.
