Every individual currently serving in the Massachusetts State Senate, grouped by district. The state senate is one of the two chambers of the Massachusetts state legislature.

Use the party filter to narrow the roster, switch between the card grid and the compact list, or open a district to see the seat's current holders. The full machine-readable roster is published as a versioned JSON dataset for downstream researchers and language models.
