How to Use This Knoxville, Maryland Map

This interactive map shows the street layout and satellite imagery for Knoxville, Maryland. 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 Maryland 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 Knoxville.

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.

About Knoxville, Maryland

Knoxville is a locality in Frederick County, Maryland, United States. It has a population of approximately 1,200. The population density is 55.0 people per km². Knoxville is located at 39.3270°N, 77.6642°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 21758.

Knoxville occupies a narrow, verdant corridor where the Potomac River carves a deliberate path through the rugged terrain of the Maryland landscape. It lies 12.6 miles west-southwest of Ballenger Creek, MD (from Ballenger Creek, MD: bearing 256°T), and is situated 2.1 miles west-northwest of Brunswick.

The current of the Potomac River serves as the primary pulse of Knoxville, defining the moisture in the air and the low-hanging mist that clings to the valley floor during the early morning hours. Beyond the immediate riverbanks, the land rises into the quiet expanse of Pleasant Valley, where the ground is marked by the infrastructure of MD State Highway Administration 1, an area that reflects the functional, utilitarian character of the region. To the west, the distant silhouettes of the Blue Ridge Mountains provide a permanent, jagged backdrop to the horizon, while the more adventurous may find their way toward the paths of the Loudoun Heights Trail to observe the intersection of water and stone from a higher vantage. The quality of light here is often heavy and amber, catching the metallic sheen of the rail lines that once dictated the movement of goods and people through this corridor.

Knoxville emerged as a product of the industrial necessity of the nineteenth century, growing primarily as a crucial rail hub where the labor of its residents was tied to the relentless schedule of the locomotives. While the economy has shifted away from the soot and steam of its formative years, the physical remnants of that era—sturdy brickwork and the remnants of rail yards—continue to anchor the visual identity of Knoxville. Life moves in accordance with the steady, unhurried pace of a place that has learned to exist in the shadow of the mountains and the constant flow of the river. It is a locality defined by its transit history, where the modern traveler might still recognize the echoes of the past in the quiet stretches of track and the way the shadows lengthen across the valley as the day wanes toward the distant, darkened ridges.

About This Knoxville Map Page

This page provides an embedded street and satellite map of Knoxville, Maryland. Coordinates: 39.327046, -77.664158. 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 Knoxville includes the ZIP code (21758), telephone area code (410, 443), county seat of Frederick County (Frederick), and school district assignment.

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.
