If you’re staring at a map of the Garden State trying to figure out where is Flemington NJ located, you’re basically looking for the bullseye of Hunterdon County. It's not one of those shore towns where you can smell the salt air, and it's definitely not a concrete jungle extension of Jersey City. Honestly, it’s a weirdly perfect little pocket of the state that feels like a time capsule until you hit the big box stores on the outskirts.
Flemington is a borough. It’s also the county seat. Geographically, it’s sitting at approximately 40.51° N and 74.86° W. If those numbers don't mean much to you, just think of it as being smack in the middle of Western New Jersey, about midway between New York City and Philadelphia.
The Doughnut Hole Geography
Here is the first thing that trips people up: Flemington is tiny. It’s only about 1.1 square miles.
Because of some old-school New Jersey "home rule" quirks, the borough is completely surrounded by Raritan Township. In local lingo, it’s called a doughnut town. Flemington is the hole; Raritan Township is the doughnut. If you cross the street to go to a specific grocery store, you might actually be leaving Flemington and entering Raritan without even realizing it.
You’ll find it nestled in the Amwell Valley. The South Branch of the Raritan River cuts through the area, and if you head just a bit northwest, you start climbing onto the Hunterdon Plateau. It’s hilly, green, and—if we’re being real—a bit of a pain to drive through if you hate roundabouts.
Getting There (and Why People Get Lost)
Most people find Flemington by following Route 202 or Route 31. These two major veins intersect right at the town's famous "Flemington Circle."
- From New York City: It’s about 55 miles away. You’d usually take I-78 West and then drop down Route 31.
- From Philadelphia: You’re looking at roughly 50 miles. Usually, that’s a straight shot up I-295 and Route 202.
- From Trenton: Just a quick 25-minute drive north.
Public transit is… well, it’s a bit of a challenge. There isn’t a direct train station right in the borough anymore. If you want the rails, you usually have to drive 15 minutes to Raritan (the town, not the township) for the NJ Transit Raritan Valley Line. Otherwise, locals rely on Trans-Bridge Lines, which runs buses directly into Port Authority in Manhattan.
A History That’s Actually Interesting
Don't let the "quaint" label fool you. This spot has seen some heavy stuff.
Back in 1935, the entire world was looking at a single building on Main Street: the Hunterdon County Courthouse. This was the site of the Lindbergh Kidnapping Trial. Bruno Richard Hauptmann was tried there for the abduction of Charles Lindbergh’s baby. It was dubbed the "Trial of the Century." During the proceedings, the Union Hotel across the street was so packed with reporters and celebrities that people were sleeping in the hallways.
The hotel still stands, though it’s been through a lot of "will-they-won't-they" renovation drama over the last decade.
Before the lawyers and the cameras arrived, Flemington was a hub for agriculture and glass. Samuel Fleming, the guy the town is named after, bought the land in 1712. He built a house called "Fleming Castle" (which is still there at 5 Bonnell Street), though it looks more like a sturdy colonial home than a medieval fortress.
What Most People Get Wrong About the Area
When people ask where is Flemington NJ located, they often assume it’s just one giant shopping mall. That’s because, for years, Flemington was the king of "Liberty Village," the first outlet shopping center in the country.
But things have shifted.
The outlets aren't the powerhouse they used to be. Today, the "location" is more about the lifestyle. It’s where people go when they want a Victorian house with a wrap-around porch but still need to be able to commute to a corporate job in Bridgewater or Princeton.
It’s also surprisingly artsy. The old Stangl Pottery factory on Mine Street—where those famous hand-painted plates were made for decades—is now a cool mix of an art gallery, a coffee shop, and a farmers market. It’s the kind of place where you can find a $7 latte and a $500 handmade vase in the same building.
Life at the Crossroads
So, what is it actually like being there?
Main Street is the heart. It’s got that "Stars Hollow" vibe, with massive Greek Revival and Victorian buildings. About 65% of the borough is on the National Register of Historic Places. That means you can’t just go painting your house neon green without someone having a conversation with you.
On Saturday nights, the town feels different. In the summer, you’ve got the Main Street Car Shows, where hundreds of classic cars line the curbs. In the winter, it’s the tree lighting that brings everyone out.

It’s a mix of:
- Commuters who work in pharma or tech.
- Artists who like the industrial-chic vibe of the old kilns.
- History buffs who can tell you exactly which chair the jury sat in during the 1930s.
Why the Location Matters Now
In the 2020s, Flemington has seen a bit of a surge.
With more people working from home, the "middle of nowhere" vibe of Hunterdon County became the "middle of everywhere" vibe. You get the space of the suburbs but you’re still within striking distance of the cultural hubs.
Also, it’s a gateway to the Delaware River. If you drive 20 minutes west, you’re in Lambertville or New Hope, PA. Drive 20 minutes east, and you’re in the suburban sprawl of Somerset County. It’s the transition point where the New York City suburbs finally give way to the rolling hills and horse farms of rural Jersey.
Real Talk: The Roundabout Situation
If you’re visiting, you need to know about the Flemington Circle.
It’s a rite of passage. It’s where Route 202, Route 31, and Route 12 all meet. It’s not a modern, polite European roundabout. It’s a Jersey circle. People are aggressive. People don’t use blinkers. If you survive the circle, you’ve officially arrived in Flemington.
How to Spend a Day Here
If you've found your way to where Flemington is located, don't just stay on the highway.
- Park on Main Street. Walk past the courthouse and look at the architecture. It’s genuinely impressive.
- Hit the Samuel Fleming House. It’s the oldest building in town and gives you a sense of what this place looked like when it was just a tavern in the woods.
- Go to Northlandz. Seriously. It’s on Route 202. It’s the world’s largest model railroad. Even if you think you don't like trains, the sheer scale of the tiny mountains and bridges is mind-blowing.
- Grab lunch at the Stangl Factory. There’s a distinct "old-meets-new" energy there that explains the town's current identity better than any map could.
Moving Forward in Flemington
Understanding where is Flemington NJ located is really about understanding the balance between history and growth. The town is currently undergoing a massive redevelopment project called "Union Village" to bring more residents and retail back to the historic core.
If you are planning a visit or thinking about moving to the area, start by exploring the Historic Flemington walking tour maps available online. They provide the exact coordinates for over 30 significant landmarks within that one-square-mile borough.
Check the local event calendar for the Hunterdon County Chamber of Commerce. If you can time your visit with a festival or a car show, you’ll get a much better feel for the community than just driving through the "doughnut" on your way to somewhere else.
To get the best experience, approach the town from the south on Route 202 during sunset. The way the light hits the Hunterdon Plateau as you descend into the Amwell Valley makes it very clear why Samuel Fleming decided to stop and build a tavern right here three centuries ago.
