If you look at a Long Island town map, you’re probably going to get a headache within five minutes. It’s not your fault. The geography here is a mess of overlapping jurisdictions, historical quirks, and names that sound exactly the same but mean totally different things. Honestly, even people who have lived in Nassau or Suffolk for thirty years still get confused about where a "town" ends and a "village" begins. It’s a jigsaw puzzle where the pieces were cut by people who didn't talk to each other for three centuries.
Long Island is roughly 118 miles long. It’s skinny. But inside that stretch, you have two massive counties—Nassau and Suffolk—that contain 13 official "towns." That sounds simple enough, right? Wrong. Because those 13 towns are actually giant administrative umbrellas that cover nearly 100 incorporated villages and hundreds of "hamlets." When you pull up a Long Island town map on your phone, you're usually seeing a simplified version that ignores the legal reality of who actually picks up your trash or fixes the potholes.
Why Your GPS Is Lying to You About Town Borders
You’ve probably noticed that your mail says one thing, but your tax bill says another. That’s the "Hamlet vs. Village" trap.
In New York State law, a "Town" is a major division of a county. For example, the Town of Hempstead is huge—it has more people than some entire states. But inside Hempstead, you might live in the Village of Garden City. Garden City has its own mayor, its own police, and its own rules. Then, right next door, you might be in a place like Levittown. Levittown isn't a town. It isn't even a village. It’s a "census-designated place" or a hamlet. On a standard Long Island town map, Levittown looks like its own entity, but legally, it’s just a neighborhood inside the Town of Hempstead.
This matters for more than just trivia. It dictates your schools, your taxes, and whether or not you can park at the local beach.
The Nassau County Breakdown
Nassau is the western half, hugging Queens. It’s dense. It’s fast. It’s also surprisingly small in terms of actual town count. You only have three towns here: Hempstead, North Hempstead, and Oyster Bay. Plus two cities—Long Beach and Glen Cove—which operate completely independently of the towns.
If you're looking at a Long Island town map of Nassau, you’ll see Oyster Bay stretching from the posh North Shore (the "Gold Coast") all the way down to the South Shore. It’s a vertical stripe that cuts the island in half. Most people think Oyster Bay is just a cute village with a harbor. It is. But it’s also a massive township that governs Massapequa, miles and miles to the south. It’s weird. It’s Long Island.
The Suffolk County Spread: Where Things Get Huge
Once you cross the border into Suffolk, the map opens up. The towns get bigger, the roads get longer, and the "town" identity starts to feel a bit more distinct. Here, you have ten towns.

Brookhaven is the absolute behemoth of the group. It takes up a massive chunk of central Suffolk. If you’re driving on the Long Island Expressway, you can be in Brookhaven for what feels like an eternity. It spans from the Long Island Sound to the Atlantic Ocean. When people use a Long Island town map to plan a move, they often underestimate Brookhaven because it contains so many different "vibes." You have the academic energy of Stony Brook on one side and the laid-back beach feel of Mastic on the other.
Then you have the East End. This is where the island splits into the North and South Forks.
Riverhead is basically the gateway. Beyond that, the map becomes a battle of the "Hamptons." Southampton and East Hampton are the towns, but they contain famous villages like Sag Harbor or Quogue. If you’re looking at a map and trying to find "The Hamptons," you won't find a single spot labeled that way. It's a collection of villages within those two eastern towns.
The Shelter Island Outlier
Don't forget the little guy. Shelter Island sits nestled between the two forks. It is its own town. It’s tiny, accessible only by ferry, and has a population that fluctuates wildly between January and July. On a Long Island town map, it looks like a little pebble dropped in the Peconic Bay. But it has the same legal standing as the Town of Hempstead. That’s the kind of inconsistency that makes mapping this place so fascinating.
Getting the "Gold Coast" and "South Shore" Straight
Most people don't use town names when they talk about where they live. They use "Shores."
The North Shore is the "Gold Coast." Think The Great Gatsby. This area, mostly in the Towns of North Hempstead, Oyster Bay, Huntington, and Smithtown, is hilly and wooded. The coastline is jagged with harbors and inlets.
The South Shore is flat. It’s all about the Great South Bay and the barrier islands like Jones Beach and Fire Island. The Towns of Babylon, Islip, and Brookhaven dominate this side. If you look at a Long Island town map and see a straight line, that’s likely the South Shore. If you see a squiggly, messy line, that’s the North Shore.

There’s a real cultural divide here. North Shore people have "harbors." South Shore people have "canals."
The Hidden Layers of a Long Island Town Map
If you really want to understand the geography, you have to look at the school districts. This is the "secret" map of Long Island.
School district boundaries almost never align perfectly with town or village borders. You could live in the Town of Oyster Bay but be in the Syosset School District. Or maybe you're in the Jericho district but have a Westbury mailing address. This is why a simple Long Island town map is often useless for homebuyers. You need a multi-layered map that shows:
- Town boundaries (For general services like trash and zoning)
- Village boundaries (For local police and building permits)
- School district lines (For your property tax bill and where the kids go)
- Post Office zones (Which determine your "address" but nothing else)
It’s entirely possible to live in one town, go to school in another, and have a zip code associated with a third. It sounds like a joke, but it’s the reality for thousands of people in places like Hicksville or Ronkonkoma.
Why Fire Island Changes Everything
Look at the very bottom of your Long Island town map. See that long, thin strip of sand? That’s Fire Island. It looks like it should be its own thing, but it’s actually carved up between the Towns of Babylon, Islip, and Brookhaven.
The famous Fire Island Pines and Cherry Grove? Those are in Brookhaven. Ocean Beach? That’s an incorporated village within the Town of Islip. Robert Moses State Park? That’s at the western tip, but it’s managed by the state, even though it’s physically in the Town of Babylon.
It’s a nightmare for delivery drivers, but it’s a dream for people who love weird geographic trivia.

Navigating the "Pine Barrens" Void
In the middle of Suffolk County, there’s a big green space on the map. This is the Central Pine Barrens. It covers over 100,000 acres. While it spans several towns—mostly Brookhaven, Riverhead, and Southampton—it’s governed by a special commission.
When you're looking at a Long Island town map, this area looks empty. But it’s the reason Long Island has clean drinking water. The aquifer sits right under those pines. So, while it doesn't have the "town" feel of a place like Mineola or Patchogue, it's arguably the most important part of the map. Without the Pine Barrens, the towns wouldn't exist because nobody would have water to drink.
How to Actually Use a Map for Planning
If you're visiting or moving, don't just look for a "Town of X" label. You need to look for the "Points of Interest" and the train stations.
The Long Island Rail Road (LIRR) is the real backbone of the Long Island town map. The branches—the Ronkonkoma Branch, the Montauk Branch, the Port Washington Branch—dictate how the island grew. Most major town centers are built around these tracks. If a town doesn't have a train station (looking at you, Bayville), it usually stays smaller, quieter, and harder to get to.
Actionable Insights for Your Next Search
- Check the "Village" status: If you're looking at a map and see a shaded area inside a town, check if it's a village. This usually means higher taxes but better services (like private snow plowing).
- Ignore Zip Codes: A zip code like 11791 (Syosset) can span multiple towns. Never rely on a zip code to tell you which town you are in. Use an official county "GIS" map for the real data.
- North vs. South: Remember that the "Town of Huntington" sounds like one place, but it stretches from the posh Huntington Bay on the Sound down to the suburban sprawl of Melville. The map is vertical; the culture is horizontal.
- The "Unincorporated" Label: If your town map says "Unincorporated," it just means the Town government (like the Town of Islip) handles everything directly. There is no middle-man village government. This is usually cheaper for taxes.
Understanding a Long Island town map requires realizing that the lines are more like suggestions than hard borders. It’s a historical layering of 300 years of English and Dutch settlement, colonial patents, and modern suburban planning. Once you stop looking for a "clean" map and start looking for the overlaps, the whole island finally starts to make a little bit of sense.
To get the most accurate view of these borders, your best bet is to avoid the generic travel maps and head straight to the Nassau County Land Records Viewer or the Suffolk County GIS portal. These are the "true" maps used by surveyors and real estate pros. They show the actual property lines and jurisdictional boundaries that Google Maps often glazes over. If you're trying to figure out if that house is in a specific school district or town, these government tools are the only way to be 100% sure.
