How to Use This Port Jefferson, Ohio Map
This interactive map shows the street layout and satellite imagery for Port Jefferson, Ohio. 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 Ohio 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 Port Jefferson.
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.

ZIP code: 45360.Port Jefferson occupies a quiet stretch of land where the Great Miami River carves a deliberate path through the fertile, inland plains of western Ohio. It lies 4.4 miles northeast of Sidney, OH (from Sidney, OH: bearing 46°T), and is situated 9.5 miles west of De Graff. The landscape around Port Jefferson remains defined by the steady, unyielding movement of this river, which brings a cool, moisture-laden air to the valley floor even during the height of the summer heat. While the jagged peaks of Bristol Ridge remain a distant, hazy suggestion on the horizon, the immediate terrain consists of expansive, productive fields that catch the long, slanted light of dusk in a way that turns the golden stalks of corn into burnished copper. A few miles to the east, the stillness of Tawawa Lake offers a sharp contrast to the constant, fluid motion of the river, acting as a mirror for the changing skies above the horizon.
Economic life in Port Jefferson historically grew from the necessity of harnessing the power of the water, and the rhythms of the present day still echo the industry of earlier generations who worked the mills and the soil. The nearby Shelby Oaks Golf Course provides a manicured buffer of green space, where the meticulously maintained fairways offer a modern, recreational counterpoint to the wilder, wooded banks of the Great Miami River. Life here proceeds with a measured intensity, where the change of seasons dictates the pace of work and the transition of the landscape from vibrant growth to the muted, gray palette of winter. The people of Port Jefferson maintain a quiet connection to this geography, recognizing the endurance of the land that has supported the settlement since its earliest days of clearing the woods and establishing a foothold in the basin.

About This Port Jefferson Map Page
This page provides an embedded street and satellite map of Port Jefferson, Ohio. Coordinates: 40.328661, -84.094386. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.
Detailed location data for Port Jefferson includes the ZIP code (45360), telephone area code (937), county seat of Shelby County (Sidney), and school district assignment (Sidney City School District).
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.
