Massachusetts's 1st congressional district is a United States congressional district located in the western and central part of Massachusetts. The state's largest congressional district in area, it covers about one-third of the state and is more rural than the rest. It has the state's highest point, Mount Greylock; the district includes the cities of Springfield, West Springfield, Pittsfield, Holyoke, Agawam, Chicopee and Westfield.

The shape of the district underwent some changes effective from the elections of 2012, after Massachusetts congressional redistricting to reflect the 2010 census.^[3] The old 1st and 2nd districts were essentially merged, placing most of western Massachusetts in a single district. The entire Springfield area is included in the new 1st district, and the Worcester County areas of the old 1st district were split between the new 2nd and 3rd districts.

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