1851–52 Massachusetts gubernatorial election

The 1851–52 Massachusetts gubernatorial election consisted of an initial popular vote held on November 10, 1851, followed by a legislative vote conducted on January 12, 1852. Incumbent Democrat Governor George S. Boutwell was reelected to a second term in office. The ultimate task of electing the governor had been placed before the Massachusetts General Court because no candidate received the majority of the vote required for a candidate to be elected through the popular election.

Although Whig nominee Robert C. Winthrop had won a plurality of the popular vote, he did not win the election because he failed to win the outright majority required to be elected through the popular vote and ultimately placed second in the resulting legislative vote after a coalition of Free Soil and Democratic Party legislators partnered to elect Boutwell to a second term.
