You're probably sitting there, staring at a piece of mail or a tax form, wondering: what county is Somerville in? It’s a simple question. But honestly, the answer depends entirely on which Somerville you’re actually talking about.
Most of the time, when people search for this, they’re thinking of the vibrant, densely packed city right outside of Boston. If that’s you, the answer is Middlesex County.
But here’s the thing. There are at least half a dozen "Somervilles" scattered across the United States. If you’re in New Jersey, Alabama, or Tennessee, you’re looking at a completely different map. It’s kinda wild how many places share the name.
The Big One: Somerville, Massachusetts
If you are in the Northeast, Somerville is that quirky, artsy city bordering Cambridge and Boston. It’s famous for its "seven hills," its incredible food scene in Union Square, and the fact that it is the most densely populated spot in all of New England.
Basically, it’s tucked into the eastern part of Middlesex County.

Middlesex is a massive county—one of the most populous in the country—and Somerville is one of its crown jewels. Even though it’s only about 4 square miles, it feels way bigger because of how many people are squeezed in. In fact, after New York City, Somerville has more artists per capita than any other city in the U.S. That’s a lot of creativity for one little corner of Middlesex.
Why people get confused here
Part of the confusion stems from how closely Somerville is tied to Boston. Boston is in Suffolk County. Because you can walk from Somerville into Boston in about twenty minutes, people naturally assume they’re in the same county. They aren't. As soon as you cross that line near Sullivan Square or Lechmere, you've jumped from Suffolk to Middlesex.
The "Other" Somervilles You Might Be Looking For
Not everyone is looking for the Massachusetts version. If you’re checking a property deed or looking for a courthouse, you might be in one of these spots:
- New Jersey: If you’re in the Garden State, Somerville is the county seat of Somerset County. It’s a classic "Main Street" town with a totally different vibe than its Massachusetts cousin.
- Tennessee: Down south, Somerville is the county seat of Fayette County. It’s part of the Memphis metropolitan area.
- Alabama: This one is a small town in Morgan County. Fun fact: it used to be the county seat back in the 1800s before things moved to Decatur.
- Texas: If you’re looking for the city near the big lake, Somerville, Texas, is located in Burleson County.

In states like Florida or California, the county is everything. They run the sheriffs, the roads, and the schools. In Middlesex County, however, the "county" is mostly a geographic boundary and a judicial district. Most of the heavy lifting—police, fire, trash, schools—is handled by the City of Somerville itself.
You’ll see "Middlesex" on your deed at the Registry of Deeds or if you’re called for jury duty at the Middlesex Superior Court. Other than that? You probably won't interact with the county much at all.
