The 1871 United States Senate election in Massachusetts was held on January 17, 1871. Incumbent Republican Senator Henry Wilson was re-elected easily to a third term as a member of the Republican Party. Wilson would not finish the term, since he was elected Vice President of the United States in 1872.
At the time, Massachusetts elected United States senators by a majority vote of each separate house of the Massachusetts General Court, the House and the Senate.
