Who Represents Newton
Newton is big enough to be split among several legislative districts. At the State House, one senator and three representatives cover the city, so the representative for your street depends on your ward and precinct. In Washington, the whole city sits in one congressional district, alongside the Commonwealth’s two U.S. senators. Use the lookup tool below to find the exact people who represent your address.

At the State House
State Senator Cynthia Stone Creem, the Senate Majority Leader, represents most of Newton. Three House districts divide the city: Amy Sangiolo in the 11th Middlesex, Greg Schwartz in the 12th Middlesex, and John J. Lawn Jr. in the 10th Middlesex, which Newton shares with Watertown and Waltham. Because the city is split, the lookup above is the surest way to find the representative for your block.
In Washington
All of Newton sits in the 4th Congressional District, represented by U.S. Representative Jake Auchincloss, a Newton resident who has held the seat since 2021. Massachusetts is represented in the U.S. Senate by Elizabeth Warren (senior senator, since 2013) and Edward J. Markey (junior senator, since 2013).

What this seat decides
The state and federal seats
Your State Representative and your State Senator. State law: the driving age, the minimum wage, the bottle deposit, and Chapter 70, the formula that decides how much state money your schools get. They also carry a home rule petition to the State House when your town votes for something state law does not yet allow it to do.
Your member of Congress and your two US Senators. Federal law and federal money, and help with a federal agency like Social Security, the VA, or immigration when someone in your family needs it. They also nominate candidates to the US service academies.
