2018 Maine House of Representatives election

The 2018 Maine House of Representatives elections took place as part of the biennial United States elections. Maine voters elected state representatives in all 151 of the state house's districts, as well as non-voting members from the Passamaquoddy Tribe and the Houlton Band of Maliseet Indians. State representatives serve two-year terms in the Maine State House.

A primary election on June 12, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the Maine Secretary of State's website.
