What are the congressional districts of Massachusetts and who represents each district in 2025?
Executive summary
Massachusetts has nine U.S. congressional districts in the current map used since the 2022 elections; commonly listed incumbents as of January 2025 include Richard Neal (1st), Jim McGovern (2nd), Lori Trahan (3rd), Jake Auchincloss (4th), Katherine Clark (5th), Seth Moulton (6th), Ayanna Pressley (7th), and (per listings) Stephen F. — with GovTrack and Wikipedia showing the state’s nine representatives in 2025 (Massachusetts maps reflect the 118th Congress boundaries). The official MassGIS district layer shows the 118th-district boundaries that took effect beginning with the 2022 elections [1] [2] [3].
1. What the map and official data say about districts
Massachusetts’ congressional districts for the 118th Congress (the map in effect starting with the 2022 elections) are published as a state GIS datalayer by MassGIS; that layer is the authoritative digital representation of the district boundaries used in state systems and reflects the districts “that went into effect beginning with the 2022 elections” [3]. The Massachusetts Secretary of the Commonwealth and the state legislature also publish district maps and download files for public use [4] [5].
2. Who represents each district in 2025 — compiled from available listings
Public listings that summarize members for January 2025 include a roster that names individuals by district: 1st — Richard Neal (D); 2nd — Jim McGovern (D); 3rd — Lori Trahan (D); 4th — Jake Auchincloss (D); 5th — Katherine Clark (D); 6th — Seth Moulton (D); 7th — Ayanna Pressley (D); 8th — (listed in snippets as Stephen F. — incomplete in provided excerpts); 9th — (not fully shown in provided snippets). These names and the statement that Massachusetts has nine representatives are reported in aggregated reference pages such as Wikipedia’s list of U.S. representatives from Massachusetts and GovTrack’s Massachusetts member pages [1] [6]. Note: the provided sources show full listings for many districts but the search snippets in this dataset do not display complete, confirmed names for every district [1] [6].
3. Where the reporting is complete and where gaps remain
The Wikipedia snippet explicitly lists 1st through 7th districts and names incumbents like Neal, McGovern, Trahan, Auchincloss, Clark, Moulton, and Pressley “as of January 2025” [1]. GovTrack maintains individual district/member pages and confirms districts and maps (for example, pages for MA-1, MA-2, MA-4, MA-5) and states the state has nine representatives [7] [8] [9] [10] [6]. However, the specific full names for the 8th and 9th districts or a single consolidated, fully visible roster for all nine seats are not fully shown in the provided search snippets; those particular entries are incomplete in the current set of sources [1] [6].
4. Competing sources and reliability
MassGIS (a Massachusetts state site) supplies the official district boundary datalayer used by the state and developed by the Special Joint Committee on Redistricting; that makes it the most authoritative source for maps and boundaries [3]. GovTrack and Wikipedia serve as commonly used secondary references for who holds each seat and include regularly updated rosters; GovTrack also provides per-district pages and embedded maps [6] [7] [8] [9] [10]. When official government rosters (e.g., the Secretary of the Commonwealth or the House of Representatives roll) are available they should be used to confirm incumbent names; the available results here point to those official datasets but do not reproduce a fully verified, complete 9-member list in the provided snippets [4] [5].
5. How to verify the missing details
To confirm the full, up-to-date list of all nine incumbents and any midterm changes after January 2025, consult the state’s MassGIS district layer for boundary questions and the official congressional roster maintained by the Clerk of the U.S. House, the Massachusetts Secretary of the Commonwealth election pages, or GovTrack member pages for each district [3] [4] [6]. The Wikipedia list is useful as a quick reference and explicitly lists many incumbents as of January 2025 [1].
6. Context and what to watch for next
Massachusetts has retained nine House districts under the current maps that took effect in 2022; congressional districts can change only after reapportionment and redistricting tied to the decennial census or via state legislative action, so the 118th-district boundaries remain the official framework until a new redistricting process occurs [3] [2]. For the most precise, legally authoritative answers about incumbency on a given date, use official government rosters and the MassGIS shapefiles cited above [3] [4].
Limitations: the provided search results clearly identify the districts and many incumbents [1] [6] [3] but do not include a single, fully visible, complete roster for all nine districts within these snippets; therefore any missing district names are not invented here—available sources do not mention the full names for some districts in the snippets provided [1] [6].
