1958 Arizona House of Representatives election

The 1958 Arizona House of Representatives elections were held on November 4, 1958. Voters elected members of the Arizona House of Representatives in all 80 of the state's House districts to serve a two-year term. The elections coincided with the elections for other offices, including Governor, U.S. Senate, U.S. House, and State Senate. Primary elections were held on September 9, 1958.

Prior to the elections, the Democrats held a majority of 58 seats over the Republicans' 22 seats. Democrats gained a seat mid-session when Representative Hathcock changed party from Republican to Democrat.

Following the election, Democrats maintained control of the chamber with 55 Democrats to 25 Republicans, a net gain of three seats for Republicans.

The newly elected members served in the 24th Arizona State Legislature, during which Democrat W. L. "Tay" Cook was chosen as Speaker of the Arizona House.
