# Massachusetts's 8th congressional district

Massachusetts's 8th congressional district is located in eastern Massachusetts, including part of Boston. It is represented by Democrat Stephen Lynch. For one congressional term (1791–1793), it served as the home district of the District of Maine. The district boundaries were significantly changed, as of the elections of 2012, due to redistricting after the 2010 census, with the old 8th district largely being shifted to the new 7th district. The new 8th district comprises many of the communities of the old 9th district, as well as some easternmost Norfolk County communities and northernmost Plymouth County communities of the old 10th district.
This district has the distinction of being the only one ever represented by someone who had previously served as president of the United States, as John Quincy Adams held this office after leaving the presidency from 1843 until his death in 1848.
