2018 Minnesota House of Representatives election

The 2018 Minnesota House of Representatives election was held in the U.S. state of Minnesota on November 6, 2018, to elect members to the House of Representatives of the 91st Minnesota Legislature. A primary election was held in several districts on August 14, 2018. The election coincided with the election for governor, a special election for the Minnesota Senate, and other elections.

The Minnesota Democratic–Farmer–Labor Party (DFL) won a majority of seats, ending the Republican majority that began with the 2014 election. The new legislature convened on January 8, 2019.

Background
The last election resulted in the Republicans winning a majority of 76 seats, increasing the majority of 72 seats it won in 2014. It was the first time that a party has retained control of the House of Representatives since the DFL in the 2008 election. In conjunction with the result of the Senate election, it also resulted in the return of all-Republican control of the Legislature since 2012—only the second time the Republicans have held control of both houses since the return of partisan elections to the House in 1974 and the Senate in 1976 and marking the end of two years of split control between a Republican-held House and a DFL-held Senate.

A special election was held for District 32B on February 14, 2017, following the invalidation of its general election results. On September 8, 2016, the Minnesota Supreme Court found Republican incumbent Bob Barrett ineligible for election because he did not reside in his district. As the ruling occurred within 80 days of the general election, Barrett's name could not be replaced on the ballot. Republican Anne Neu won the special election, increasing the Republican majority to 77 seats.

Electoral system
The 134 members of the House of Representatives were elected from single-member districts by first-past-the-post voting to two-year terms. Contested nominations of the DFL and Republican parties for each district were determined by an open primary election. Minor-party and independent candidates were nominated by petition. Write-in candidates had to file a request with the secretary of state's office for votes for them to be counted. The filing period was from May 22 through June 5, 2018.
