You’re driving down Route 22, maybe grabbing a quick bite at the White Castle or checking out the shops at the Somerset Shopping Center, and you start wondering where exactly you are on the map. It's a common headache. North Plainfield is one of those places that feels like it belongs to three different worlds at once. People constantly mix it up.
So, let's settle the debate right now. North Plainfield is in Somerset County. It sounds simple, but the confusion is real. You’ve got Plainfield right next door, which is in Union County. Then you have South Plainfield just a stone's throw away in Middlesex County. It’s a geographical triangle that trips up even lifelong Jersey residents. Honestly, if you’ve ever filled out a form and hesitated before checking the county box, you aren’t alone.
The Great County Identity Crisis
The reason everyone gets confused about what county North Plainfield NJ is in usually boils down to the name. We tend to think of "The Plainfields" as one big unit. In reality, they are split across three separate county lines.
North Plainfield is a borough. It’s compact, covering about 2.8 square miles, but it packs a lot of history into that small footprint. It officially broke away from Warren Township back in 1872. Back then, the area was mostly farmland and "the plains" under the Watchung Mountains. Today, it’s a bustling suburb with a population hovering around 22,000 people.
Living here feels different than living in the heart of Somerville or the farmlands of western Somerset. It has a "dense suburban" vibe, as the experts at Niche like to call it. You have the mountains—technically the Watchung Ridges—looming over the north side of town, while the southern border is defined by the Green Brook. That little stream isn’t just a waterway; it’s the literal line between Somerset and Union County. Cross the bridge, and you're in a different jurisdiction.
A Quick Geography Cheat Sheet
- North Plainfield: Somerset County (The one with the mountain views).
- Plainfield: Union County (The "Queen City").
- South Plainfield: Middlesex County (Home of the big warehouses and suburban sprawl).
Why the Somerset Connection Matters
You might think, "Who cares what county I'm in as long as the mail arrives?" Well, in New Jersey, your county is your lifeblood for services.
Being in Somerset County means North Plainfield residents are part of one of the wealthiest and most highly-ranked counties in the country. We're talking about top-tier park systems and solid infrastructure. The Somerset County Library System is a huge perk here. The North Plainfield branch on Somerset Street is a local staple, and because it’s part of the larger county network, you get access to a massive collection of books and digital resources that a smaller town couldn't afford on its own.
Then there’s the political side. The borough is governed by a Mayor and a seven-member Borough Council. Currently, Lawrence La Ronde sits in the Mayor’s seat. They handle the hyper-local stuff—potholes, snow removal on Somerset Street, and local zoning—but the bigger regional issues like the Superior Court system or certain social services go through the county seat in Somerville.
The Vibe of the Borough
North Plainfield isn't just a dot on a map. It’s got a personality. It’s way more diverse than people realize. According to recent census data, over half the population identifies as Hispanic or Latino, and there’s a massive South American community here.
Walking down the street, you’ll hear a mix of Spanish and English. You’ll smell incredible food. It’s a "walking town" in many parts, especially the East side near the border. If you’re looking for a 100-year-old Victorian house with a wrap-around porch, you can find it here. If you want a modern apartment close to the bus line to New York, that’s here too.
Notable Faces You Might Recognize
Believe it or not, some pretty famous people have called this 2.8-mile stretch home:
- John DiMaggio: The voice of Bender from Futurama. Yeah, he’s from here.
- Bill Evans: The legendary jazz pianist.
- Steve Schmidt: The political strategist.
It’s a weirdly high concentration of talent for a place most people just drive through on their way to the mall.

Real Talk: The Challenges
It’s not all sunshine and mountain views. Because North Plainfield is older and more densely packed than some of its Somerset County neighbors (like Bernardsville or Bridgewater), it faces different hurdles.
Property taxes in Jersey are legendary for being high, and North Plainfield is no exception. The school system is often a topic of heated debate at council meetings. While the town is part of the Somerset County vocational system, the local district is constantly working to balance a tight budget with a growing student population.
Also, let's talk about the Green Brook. If you live near the water, you know the "F" word: Flooding. Being at the base of the mountains means when a big storm hits, the water has to go somewhere. The borough has spent years working with the Army Corps of Engineers on flood control projects. It's a work in progress, but it’s a reality of life in this part of the county.
How to Get the Most Out of North Plainfield
If you're moving here or just visiting, don't stay on Route 22. Get off the highway.
- Check out Washington Rock State Park: It’s technically just over the line in Green Brook, but it’s the backyard for North Plainfield. The view of the New York City skyline on a clear day is unbeatable.
- Eat local: Skip the chains. There are some incredible family-owned spots along Somerset Street and Watchung Avenue that serve authentic Peruvian and Mexican food.
- Use the County Perks: If you’re a resident, get that Somerset County library card immediately. It’s basically a golden ticket for free entertainment and learning.
North Plainfield is a bit of an underdog. It doesn't have the "fancy" reputation of some other Somerset towns, but it has a grit and a community feel that's hard to find elsewhere. It’s a place where people actually know their neighbors.
Actionable Steps for Residents and Newcomers
If you need to get things done in the borough, skip the generic Google searches and go straight to the source. The Borough Hall is located at 263 Somerset Street.

Knowing you're in Somerset County isn't just about trivia; it's about knowing which sheriff's office to call and where your tax dollars are actually going. Now, the next time someone tries to tell you North Plainfield is in Union County, you can politely correct them with the facts.
