2018 Georgia House of Representatives election

The 2018 Georgia House of Representatives elections took place as part of the biennial United States elections. Georgia voters elected state representatives in all 180 of the state house's districts. State representatives serve two-year terms in the Georgia House of Representatives.

A primary election on May 22, 2018, and a runoff election on July 24, 2018, in races where no candidate received more than 50% of the vote in the May primary determined which candidates appear on the November 6 general election ballot. Primary and runoff election results can be obtained from the Georgia Secretary of State's website. A statewide map of Georgia's state House districts can be obtained from the Georgia Legislative and Congressional Reapportionment Office here, and individual district maps can be obtained from the U.S. Census here.

Following the 2016 state House elections, Republicans maintained effective control of the House with 118 members. However, over the course of 2017 and 2018, Democrats flipped District 117 and District 119 in special elections. Due to these special election loses and vacancies caused by resignation, Republican seats decreased from 118 to 115 and Democratic seats increased from 62 to 64 by election day 2018.

To have claimed control of the chamber from Republicans, the Democrats would have needed to net 27 House seats.

Following the 2018 elections, Democrats received a net gain of 11 seats, winning 14 contests and increasing their margin to 75 seats. Republicans maintained their majority, but they still suffered a net loss of nine seats as opposed to 10 when taking into account that Republican Steven Sainz filled the vacancy in District 180. The Republican majority in the Georgia State House initially stood at 104 after the election, despite winning 105 seats, due to the death of Rep. John Meadows on Nov. 13, 2018. As a result, a special election was held, with Matt Barton winning the election, bringing the Republican seat total back up to 105.
