The 2006 Arizona House of Representatives election took place on Tuesday, November 7, 2006, with the primary election held on Tuesday, September 12, 2006. Arizona voters elected all 60 members of the Arizona House of Representatives in multi-member districts 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 Senate.
Following the previous election in 2004, Republicans held a 38-to-22-seat majority over Democrats. During the legislative session, Representative Cheryl Chase switched political party affiliation from Democrat to Republican. Republicans maintained their majority in 2006, though the GOP majority narrowed to 33 seats. At 27 members, Democrats experienced a net gain of six seats. The newly elected members served in the 48th Arizona State Legislature, during which Republican Jim Weiers was re-elected as Speaker of the Arizona House.
