Massachusetts's 7th congressional district is a congressional district located in eastern Massachusetts, including roughly three-fourths of the city of Boston and a few of its northern and southern suburbs. Massachusetts congressional redistricting after the 2010 census changed the borders of the district starting with the elections of 2012, with most of the old 7th district redistricted to the new 5th district. Most of the old 8th district now comprises the new 7th district. The seat is currently held by Ayanna Pressley.
