The 2010 congressional elections in Arizona were held on November 2, 2010, to determine who would represent the state of Arizona in the United States House of Representatives. Arizona had eight seats in the House, apportioned according to the 2000 United States census. Representatives were elected for two-year terms; those elected were to serve in the 112th Congress from January 3, 2011, until January 3, 2013.
The state's 2009-2010 delegation consisted of five Democrats and three Republicans. With the exception of Democrat Ann Kirkpatrick, who had won the open seat in District 1 during the previous election, all members of the delegation were incumbents who had served for at least a full term in Congress. Also, with the exception of retiring Republican John Shadegg of District 3, all incumbent members of the state's delegation ran for re-election.
As of August 17, 2010, Districts 1, 5 and 8, all held by Democrats, were considered to be competitive by both CQ Politics and The Cook Political Report. The primary elections for Congressional races were held on August 24, 2010.

#### Campaign

Gorman gained national attention during the campaign for an ad showing her firing a Thompson submachine gun, and for her cosponsorship of the highly controversial SB 1070 anti-illegal immigration bill.
Quayle, the initial frontrunner in the race, faced criticism for his prior involvement with the controversial rumour and gossip website "DirtyScottsdale.com". According to the site's founder, Quayle was one of the "original contributors" to the site, which covered Scottsdale nightlife with features including sexy photos of women, and was the predecessor to the gossip website TheDirty.com. Quayle initially denied the rumors, before admitting several weeks later that he did, in fact, write material for the site under the pen name Brock Landers. Newcomer Steve Moak's strong fundraising and television advertising blitz against Quayle saw him to be viewed as the new frontrunner, however he faced allegations that he illegally profited from a charity he had set up, hurt his campaign.

#### Results

Quayle emerged victorious with 22.1% of the vote, while businessman and political neophyte Steve Moak came in second with 18%.

### General election
#### Campaign

Prior to Mitchell's victory over incumbent conservative Republican J. D. Hayworth in 2006, the district had been held by Republicans since 1995, although it had been tending towards the Democrats. Schweikert posted signs across the district calling Mitchell a “lap dog” for Nancy Pelosi, after Mitchell voted for the 2008 bank bailout, the $787 billion stimulus law in 2009 and the Affordable Care Act in March 2010. This despite Mitchell's breaks with the Party on a number of Tax and climate change legislation.

### Independents
#### Candidates

### General election
#### Campaign

Despite the Democratic lean of the district, Grijalva faced a tougher than expected re-election campaign following his suggestion that businesses should boycott the state in response to the passing of the highly controversial SB 1070 anti-illegal immigration bill. Both Grijalva and challenger, 28-year-old physicist Ruth McClung, benefitted from outside spending in the final weeks of the campaign, in addition to the national environment favouring the Republicans.
