The 2018 Hawaii House of Representatives elections took place as part of the biennial United States elections. Hawaii voters elected state representatives in all 51 state house districts. State representatives serve two-year terms in the Hawaii House of Representatives.
A primary election on August 11, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the State of Hawaii's Office of Elections website. A statewide map of Hawaii's state house districts can be obtained from the state's Office of Planning here, and individual district maps can be obtained from the state's Office of Elections here.
Following the 2016 state house elections, Democrats maintained effective control of the chamber with 45 members. Beth Fukumoto, former Republican Leader, switched parties and was accepted into the Democratic caucus on June 19, 2017. This increased the Democrats majority to 46 seats.
To claim control of the chamber from Democrats, the Republicans would have needed to net 21 House seats. In the end, there was no net seat change, with Democrats maintaining 46 seats.
