Massachusetts's 4th congressional district is located mostly in southern Massachusetts. It is represented by Democrat Jake Auchincloss. Auchincloss was first elected in 2020.

The district covers much of the area included in the 10th district before the 1992 redistricting. 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 the South 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 the District of Maine.
