The 2002 Arizona Senate election was held on November 5, 2002. Voters elected members of the Arizona Senate in all 30 of the state's legislative districts to serve a two-year term. These were the first elections following the 2000 redistricting cycle, which moved many incumbents into new districts. Primary elections were held on September 10, 2002.[3]
Prior to the elections, the Senate was evenly divided between the Republicans and Democrats in a 15-to-15 tie.
Following the election, Republicans took unitary control of the chamber with 17 Republicans to 13 Democrats, a net gain of two seats for Republicans.[4]
The newly elected senators served in the 46th Arizona State Legislature.
