The 2004 Arizona House of Representatives election took place on Tuesday, November 2, 2004, with the primary election held on Tuesday, September 7, 2004. 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. President, U.S. Senate, U.S. House, and Arizona Senate.
Following the previous election in 2002, Republicans held a 39-to-21-seat majority over Democrats. During the legislative session, Representative Sylvia Laughter switched political party affiliation from Democrat to Independent. Republicans maintained their majority in 2004, winning 38 seats. At 22 members, Democrats regained Laughter's seat and flipped a Republican seat, resulting in a net gain of two seats. The newly elected members served in the 47th Arizona State Legislature, during which Republican Jim Weiers was elected as Speaker of the Arizona House.
