You’re likely planning a move or just trying to figure out where that famous red lighthouse is on a map. It’s a common question because Florida’s geography can be a bit of a maze, especially with towns that feel like they belong in one world but are technically in another.
Jupiter, Florida, is located in Palm Beach County.

It’s the northernmost town in the county, perched right on the edge of the Atlantic. In fact, if you drive just a few minutes north of the Jupiter Inlet, you’ll cross the line into Martin County. That proximity is why people get confused. You’ve got this high-end, coastal vibe that bleeds into neighboring Tequesta and Hobe Sound, making the county line feel more like a suggestion than a border.
Palm Beach County: More Than Just Palm Beach
When most people hear "Palm Beach County," they think of the island of Palm Beach—Worth Avenue, massive estates, and high-society galas. But Palm Beach County is massive. It’s actually the second-largest county by land area in Florida, covering nearly 2,000 square miles. To put that in perspective, it’s bigger than the states of Rhode Island and Delaware.
Jupiter is the "crown jewel" of the north end. While West Palm Beach (the county seat) is about 20 miles south, Jupiter feels like its own ecosystem. It’s less about the urban hustle and more about the "Loxahatchee life."
The "Celestial" Connection
Here is a weird bit of trivia you won't find in most dry SEO snippets. Jupiter wasn't named because the early settlers loved astronomy. It was actually a colossal misunderstanding.

The local Hobe Indians lived near the mouth of the Loxahatchee River. Spanish explorers called them the "Jobe" (pronounced HO-beh). Later, English mapmakers saw the name "Jobe" and, thinking they were being clever, translated it to "Jove," which is another name for the Roman god Jupiter.
Basically, the town's name is a centuries-old typo that stuck.
Life on the Edge of the County Line
Being in Palm Beach County matters for things like taxes, schools, and voting, but for the people living there, the location is all about the water. Jupiter sits at the confluence of the Loxahatchee River, the Intracoastal Waterway, and the Atlantic Ocean.
- The Jupiter Inlet: This is the heartbeat of the town. Because the Gulf Stream current flows closest to the shore right here, the water is often a shocking, Caribbean-style turquoise.
- Spring Training: If you’re a baseball fan, being in this part of the county is a dream. Roger Dean Chevrolet Stadium is the only stadium in the country that hosts two MLB teams for Spring Training: the St. Louis Cardinals and the Miami Marlins.
- The Celebrity Factor: You might bump into Tiger Woods or Michael Jordan at a local spot like 1000 North. Since Jupiter is in Palm Beach County but away from the paparazzi-heavy streets of Miami, it’s become a sanctuary for the ultra-famous who just want to fish and play golf in peace.
Getting Around the North County Area
Navigation here is pretty straightforward. U.S. 1 and A1A are your primary north-south veins. If you’re heading to the courthouse or the airport (PBI), you’re heading south toward West Palm. If you’re looking for a quieter, "old Florida" feel, you head north into Martin County.
Neighbors You Should Know
- Tequesta: Often mistaken for part of Jupiter, this is a separate village just to the north.
- Juno Beach: Directly south, home to the Loggerhead Marinelife Center.
- Palm Beach Gardens: The shopping and golf hub just inland.
Why the Location Is a Big Deal for Residents
Honestly, being in Palm Beach County comes with some perks that "Jupiterites" (yes, they call themselves that) really value. The Palm Beach County School District is one of the largest and most well-funded in the state, which is a huge draw for families moving to the Abacoa or Jupiter Farms neighborhoods.
Then there’s the park system. Because Palm Beach County has deep pockets, the parks in Jupiter—like Riverbend Park and Carlin Park—are impeccably maintained. Riverbend, in particular, is a 665-acre throwback to what Florida looked like before the developers arrived. You can rent a kayak, paddle past sunbathing alligators, and forget that a bustling metro area is only 15 minutes away.

Taking the Next Step
If you’re visiting, don’t just stick to the beach. Drive out to Jupiter Farms on the western side of the town to see the equestrian side of Palm Beach County, where people trade oceanfront condos for five-acre lots and horse trails.
Check out the Jupiter Inlet Lighthouse & Museum first. It gives you the best vantage point to see exactly how the town sits within the county. You can literally see the boundaries of the Loxahatchee River and the vastness of the Atlantic from the top of the 105-foot tower. It’s the best way to get your bearings before exploring the rest of what this corner of the county has to offer.
