The 2014 United States Senate election in Massachusetts was held on November 4, 2014, to elect a member of the United States Senate to represent the Commonwealth of Massachusetts, concurrently with the election of the Governor of Massachusetts, other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. Incumbent Democratic Senator Ed Markey ran for re-election to a first full term in office. Primary elections were held on September 9, 2014. Markey was unopposed for the Democratic nomination; Hopkinton Selectman Brian Herr was also unopposed for the Republican nomination.

Background

Incumbent Democratic Senator John Kerry, serving since 1985, had planned to run for re-election to a sixth term, but on December 15, 2012, it was announced that the long-time Massachusetts senator and 2004 presidential nominee would be nominated as United States Secretary of State under President Barack Obama. Massachusetts Governor Deval Patrick appointed Mo Cowan as a temporary replacement for Kerry, after he was confirmed as secretary of state and therefore resigned his senate seat. There was a special election on June 25, 2013, to finish the term, which was won by Ed Markey, the 37-year Democratic incumbent from MA's 5th congressional district.
