Explore Smithtown, New York, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Smithtown, New York. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of New York or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Smithtown.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Smithtown possesses a distinct character defined by the winding presence of the Nissequogue River, which cuts through the terrain and shapes the local topography with its steady, tidal-influenced pulse. It lies 2.1 miles north of Hauppauge, NY (from Hauppauge, NY: bearing 3°T), and is situated 8.7 miles north of Islip. The landscape is characterized by a mix of mature woodlands and suburban stretches that open up toward the coastal proximity of Smithtown Bay, sitting just four miles away. Within the quiet corners of the residential neighborhoods, one finds Millers Pond, a serene body of water that mirrors the changing sky and serves as a local anchor for the surrounding ecosystem. While the distant Appalachian Mountains are far beyond the horizon, the immediate ground is defined by the protected expanse of County Of Suffolk Land, which preserves the natural quiet of the region against the encroaching pace of the modern world.
Smithtown traces its origins back to the mid-seventeenth century, a period when the land was established through colonial land grants that prioritized the fertile ground near the river. The early settlers recognized the value of the geography, utilizing the natural waterways for transport and the surrounding forests for timber and sustenance. Over the passing generations, the identity of Smithtown evolved from a scattering of agrarian homesteads into a structured settlement that managed to retain a sense of its original, deliberate layout. This historical progression is still legible in the older architectural styles that persist in the center of the locality, serving as a silent reminder of the laborers and families who first cleared the soil and defined the boundaries that persist to this day.
Smithtown sustains a robust local economy driven by a mix of professional services, retail centers, and a reliance on the broader infrastructure of the region. The proximity to major transit arteries allows for a steady flow of commerce, supporting a variety of industries that cater to a commuting workforce while maintaining local businesses. Education remains a cornerstone of the public identity, with local schools preparing students for higher learning and technical careers. As the infrastructure has expanded, the focus has shifted toward balancing necessary growth with the preservation of the open spaces found in the County Of Suffolk Land, ensuring that the economic vitality of Smithtown does not come at the total expense of its natural environment.
Cultural life in Smithtown is shaped by the seasonal rhythm of the coastal climate, where the air often carries a sharp, saline hint of the nearby bay. Annual community gatherings and festivals bring residents together, often utilizing the public parks and open spaces to celebrate the changing seasons or local traditions. While professional sports teams draw their primary following from the wider regional market, the local spirit is often found in high school athletics, which serve as a focal point for weekend activity. Famous landmarks, including historic structures and the natural beauty of the river banks, ground the residents in a specific sense of place, while the occasional well-known figure who has spent time in the area adds a faint layer of recognition to the local narrative.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
