The 2018 Arizona Senate election took place on November 6, 2018, with the primary election held on August 28, 2018. Arizona voters elected all 30 members of the Arizona Senate to serve two-year terms.
The election coincided with United States national elections and Arizona state elections, including U.S. Senate, U.S. House, Arizona governor and Arizona House.
Following the previous election in 2016, Republicans held a 17-to-13-seat majority over Democrats. Republicans maintained their unchanged 17-to-13 majority in 2018. The newly elected members served in the 54th Arizona State Legislature, during which Republican Karen Fann was elected President of the Arizona Senate.
