The 1978 Montana Senate election took place on November 7, 1978, with the primary election held on June 6, 1978. Montana voters elected 27 of the 50 members of the Montana Senate. The election coincided with United States national elections and Montana state elections, including U.S. Senate, U.S. House, and Montana House.
Following the previous election in 1976, the chamber was tied with both Democrats and Republicans holding 25 seats. Republicans flipped control of the chamber in 1978 by winning 26 seats while Democrats held 24—giving Republicans a net gain of one seat. The newly elected members served in the 46th Montana State Legislature, during which Republican William L. Mathers was elected President of the Montana Senate.
