1926 United States Senate special election in Massachusetts

The 1926 United States Senate special election in Massachusetts was held on November 2, 1926.

Former Democratic Senator David I. Walsh defeated incumbent William Morgan Butler, a Republican who was appointed after the death of Republican Senator Henry Cabot Lodge.

Walsh returned to the U.S. Senate for a 2-year term. He had previously served in the Senate from 1919 to 1925. This was the first time since 1851 that Democrats held this Senate seat.

Background
Senator Henry Cabot Lodge, whose sixth term was set to expire in 1929, died on November 9, 1924, after suffering a stroke. On November 13, 1924, Governor of Massachusetts Channing Cox appointed William M. Butler, the chair of the Republican National Committee, to fill the vacant seat until a successor could be duly elected. The special election for the remainder of Lodge's term was scheduled for November 2, 1926, concurrent with the next general election.

Campaign
Butler formally announced his anticipated campaign for the special election on April 22, 1926, at a rally at Boston Symphony Hall, where he was endorsed by Governor Alvan T. Fuller, Senator Irvine Lenroot of Wisconsin, and Assistant Secretary of War Hanford MacNider. Most of the speakers connected Butler's campaign to the re-election prospects of President Calvin Coolidge, a close ally of Butler.

At the Republican convention on September 24, Butler was unopposed for the nomination and received the unanimous support of the delegates.
