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. 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.
