Massachusetts's 4th congressional district is located mostly in southernMassachusetts. It is represented by DemocratJake Auchincloss. Auchincloss was first elected in2020.

The district covers much of the area included in the10th district before the 1992redistricting. In prior years, the district stretched from Brookline to Fitchburg. The shape of the district underwent some changes effective from the elections of 2012, after Massachusetts congressional redistricting to reflect the 2010 census.^[3] Most of Plymouth County and theSouth Coast are included in the new 9th district. The new 4th district has expanded westward to include towns along the Rhode Island border that had been in the old 3rd district.

For a very brief time (1793–95) it represented part of theDistrict of Maine.

There are 35 municipalities in the 4th district, as of the 2021 redistricting.^[4] This list is sorted by county.
