The 2018 Tennessee House of Representatives election was held on November 6, 2018, to elect 99 seats for the Tennessee House of Representatives. The elections coincided with the Governor, U.S. Senate, U.S. House, and State Senate elections.

Democrat Gloria Johnson flipped Knoxville's Suburban 13th district, and Democrat Bob Freeman flipped suburban Nashville's 56th district, while Republican Chris Hurt defeated Democratic minority leader Craig Fitzhugh in west Tennessee's rural 82nd district. The Republican Party maintained their supermajority in the state house.

Both the speaker and the minority leader retired, and their seats were subsequently won by the opposing party.
