The 1980 Montana House of Representatives election took place on November 4, 1980, with the primary election held on June 3, 1980. Montana voters elected all 100 members of the Montana House of Representatives to serve two-year terms. The election coincided with United States national elections and Montana state elections, including U.S. President, U.S. House, Montana Governor, and Montana Senate.
Following the previous election in 1978, Democrats held a 55-to-45-seat majority over Republicans. Republicans flipped control of the chamber in 1980 by winning 57 seats while Democrats held 43—giving Republicans a net gain of 12 seats. The newly elected members served in the 47th Montana State Legislature, during which Republican Bob Marks was elected Speaker of the Montana House.
