Massachusetts's 1st congressional district covers the western portion and the south of the central portion of the state. It is the largest and most sparsely populated district in the state, covering about 30% of the state's land area. The largest cities in the district are Springfield, Chicopee, Pittsfield, Westfield, and Holyoke.

Richard Neal, a Democrat from Springfield, represents the district; he previously represented the old 2nd from 1989 to 2013.

History of district boundaries After the 2010 census, the 1st district shifted from covering the western and north-central portions of the state to covering the western and south-central portions of the state. Following the 2020 census, the 1st district boundaries did not shift as drastically but moved to cover somewhat less of the western portions of Franklin and Hampshire Counties while encompassing more of Worcester and southeastern Hampshire Counties.
