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.
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.
The newly elected senators served in the 46th Arizona State Legislature.
