The 1964 Montana gubernatorial election took place on November 3, 1964. Incumbent
Governor of MontanaTim M. Babcock, who became Governor upon the death of previous Governor
Donald Grant Nutter, ran for re-election. He won the
Republican primary unopposed, and advanced to the general election, where he faced
Roland Renne, the former President of
Montana State College and the
Democratic nominee, in the general election. Despite the fact that then-President
Lyndon B. Johnson won the state
handily in that year's
presidential election, Babcock managed to narrowly defeat Renne to win his second and final term as governor.
