If you’re driving through the tree-lined streets of North Jersey, passing grand estates and massive corporate headquarters, you might find yourself wondering about the logistics of the place. You’ve likely seen the signs for the New York Jets training facility or the sprawling Fairleigh Dickinson University campus and thought: Florham Park NJ is in what county?
The short answer is Morris County.
But honestly, just knowing the county name doesn't tell the whole story. Florham Park is one of those places that feels like a hidden pocket of the Gilded Age tucked inside a modern suburban hub. It’s located in the southeastern part of Morris County, sitting about 30 miles west of New York City. It’s a small borough—only about 7.6 square miles—but it carries a massive reputation for its history and its neighbors.
Why Everyone Gets Confused About Florham Park
People get turned around because of the "M" towns. You’ve got Madison, Morristown, Morris Township, and Millburn all swirling around each other. Florham Park is bordered by Madison and Chatham to the south, and East Hanover to the north.
It’s easy to assume it might be in Essex County because it’s so close to Livingston and Millburn. But nope. Once you cross the Passaic River to the east, you’re in Essex. Florham Park stays firmly on the Morris County side of the water.
The Geography of the Borough
The borders are pretty distinct if you know what to look for:

- The East: The Passaic River acts as the natural boundary.
- The South: It blends almost seamlessly into Madison and Chatham.
- The North: You hit Hanover and East Hanover.
- The West: It rubs shoulders with Morris Township.
A History Born from Two Names
The name "Florham" isn't just a fancy-sounding word. It’s actually a portmanteau. It comes from Florence Adele Vanderbilt Twombly and her husband Hamilton McKown Twombly.
Florence was the granddaughter of Commodore Cornelius Vanderbilt. In the late 1890s, they built a massive 100-room mansion on a 1,200-acre estate. They called it "Florham." When the borough was officially incorporated in 1899, they took the name of the estate and added "Park" to it. Basically, you’re living in or visiting a town named after a Gilded Age power couple.
Before it was a playground for the ultra-wealthy, the area was known as "Broomtown." Why? Because the locals were famous for manufacturing brooms. It’s a funny contrast—going from a town known for straw brooms to one known for Vanderbilt mansions and Rolls Royces.
Life in Morris County Today
Morris County is consistently ranked as one of the best places to live in the United States, and Florham Park is a big reason why. It has a "Community of Volunteers" vibe. Interestingly, the mayor and council members actually serve without pay. That’s pretty rare for a town with this much corporate activity.
The Big Players
You might think of it as a quiet suburb, but some of the world's biggest companies have set up shop here. We’re talking about:
- BASF: Their North American headquarters is a massive, sustainable building right on Park Avenue.
- Conduent: A major player in business process services.
- Shionogi: A Japanese pharmaceutical company.
- The New York Jets: This is probably what the town is most famous for globally. Their Atlantic Health Jets Training Center is a state-of-the-art facility where the team practices and operates.
If you're a sports fan, you've probably seen "Florham Park, NJ" at the bottom of a news ticker during the NFL season. Even though they play their games at MetLife Stadium in East Rutherford (Bergen County), their "home" is Morris County.
Getting Around and Getting Educated
Transportation is a huge draw for people moving to this part of Morris County. You’re close to Route 24, which connects you to I-78 and the Garden State Parkway. While Florham Park doesn't have its own train station, the Madison and Chatham stations are just a few minutes away, offering a direct "Midtown Direct" line into Penn Station.
Education is another heavy hitter here. You have Fairleigh Dickinson University (FDU) occupying a huge chunk of the old Twombly estate. Walking through the campus feels like stepping back into the 1920s because they’ve preserved so much of the original architecture. Then there’s Saint Elizabeth University, which was founded by the Sisters of Charity and has its own beautiful, historic grounds.
Quick Stats (As of 2026)
- Population: Approximately 14,500 people.
- Median Household Income: Usually hovers around $147,000+.
- County Seat: Morristown (just a 10-minute drive away).
Is it Worth Visiting?
If you're into history or just want a nice place to grab dinner, yeah, it’s worth a stop. The Park Savoy Estate is one of the most famous wedding venues in the state. If you’re not there for a wedding, the local dining scene is surprisingly solid. You’ve got the Florham Park Diner for that classic Jersey experience, or more upscale spots like Lucco Cucina & Bar.

Honestly, the best thing to do is just drive down Park Avenue or Ridgedale Avenue. You get a real sense of the "Old Money" history clashing with modern corporate innovation. It’s a weird, beautiful mix that defines this corner of Morris County.
Your Next Steps
If you are looking to move to the area or just visiting for the weekend, here is what you should do:
- Check the Morris County Government site: If you need specific records or tax information, that’s your go-to.

Florham Park is more than just a spot on a map; it's a testament to how New Jersey preserves its past while keeping its eyes on the corporate future. Now you know—it's Morris County through and through.
