The 1964 Massachusetts gubernatorial election was held on November 3, 1964. Incumbent Governor Endicott Peabody ran for re-election, but was defeated by then-Lieutenant Governor Francis X. Bellotti in the Democratic Party primary. Bellotti went on to lose the general election to former Governor John Volpe. The race between Volpe and Bellotti was the first time in Massachusetts history that the two major parties backed sons of Italian immigrants for governor. This was the final election held before the governor's term of office was extended from two to four years.
