The 2018 Idaho Senate election was held on November 6, 2018, to determine which party would control the Idaho Senate for the following two years in the 65th Idaho Legislature. All 35 seats in the Idaho Senate were up for election and the primary was held on May 15, 2018. Prior to the election, 29 seats were held by Republicans and 6 seats were held by Democrats. The general election saw Democrats flip a single seat, thereby meaning that Republicans retained their majority in the State Senate.[1][2]
