The 2018 Arizona State Legislature elections were held on Tuesday, November 6, 2018. A primary election took place on August 28, 2018. Voters in all 30 legislative districts of the Arizona Legislature elected one state senator and two state representatives. The elections coincided with the elections of other offices, including for governor and the United States Senate.

Members to the state senate are elected from the same legislative districts as members of the state house of representatives; however, one senator represents the constituency, while for the house there are two representatives per district.^[1] In this election, each of the party leaders from both chambers retired, and were elected to different offices.
