Middleville

Written By Dino DiPietro

On Long Island, “Middleville” wasn’t a major town—it was a small historic hamlet/local place name on the north shore of Suffolk County, in the area of the modern Huntington, New York / Smithtown, New York border. It’s near Sunken Meadow State Park and the communities of Fort Salonga, New York and East Northport, New York.

What it actually was

  • A tiny hamlet or neighborhood name, not an incorporated village.

  • Located in Suffolk County on Long Island’s north shore.

  • The name appears on some maps and older references but is rarely used today.

Like many Long Island place names, it functioned more as a local geographic label than a formal municipality. Long Island’s structure is:

  • County → Town → Hamlet/Neighborhood
    So Middleville was just a small locality within a larger town, not a town of its own.

Why the name existed

The name likely followed a common 1700s–1800s pattern:

  • “Middleville” = settlement in the middle of other communities or roads.

  • Many early farm crossroads settlements used names like Centerville, Middle Island, Middleville, etc.

What happened to it

Over time:

  • Development and postal addresses shifted to Fort Salonga, Huntington, or East Northport.

  • The Middleville name mostly disappeared from everyday use, surviving mainly on some maps and historical references.

⚠️ Important:
Don’t confuse it with Middleville, New York in Herkimer County, New York upstate—that is an actual incorporated village with a population of about 400.

✅ In short:
“Middleville” on Long Island was just an old, small hamlet name near Fort Salonga/Northport that faded out as the area developed.

If you want, I can also show you exactly where Middleville was on an old Long Island map—it’s a neat little piece of LI geography history.
