MGM National Harbor is 7.6 miles from Washington, D.C. in straight-line distance. Road distance is always longer than straight-line distance, and this article does not publish driving mileage or travel time.
The fixed point this question is really about
The venue identified by publicly published reference sources is MGM National Harbor in National Harbor, Maryland. Its documented coordinates are 38.79483333, -77.00958333, while Washington, D.C. is documented here at 38.90472222, -77.01638889.
That makes this a location question with one measured pair: Washington, D.C. to MGM National Harbor. The useful part is the fixed geography, because the venue stays in one place while route choice, traffic, bridge use, and other trip details can change.
Documented straight-line distance
| 参照点 | 直线英里 | 测量类型 |
|---|---|---|
| Washington, D.C. | 7.6 | great-circle |
This is a great-circle measurement, sometimes called straight-line or as the crow flies. It is useful for understanding relative proximity, but it is not a road trip figure.
Where the venue sits
MGM National Harbor is in National Harbor, Maryland. Using the documented coordinates only, it sits south of Washington, D.C., because its latitude, 38.79483333, is lower than Washington's 38.90472222.
It is also slightly east of Washington, D.C., because its longitude, -77.00958333, is less negative than Washington's -77.01638889. In plain directional terms, the venue is southeast of Washington, D.C., across a state line in Maryland.
That regional positioning is often more helpful than a raw mileage figure. If you are orienting yourself from central Washington, D.C., the key idea is that the property is nearby in a neighboring jurisdiction rather than deep into another state.
Why straight-line distance and real travel differ
A straight-line measurement connects two coordinates directly over the map surface. Real travel has to follow the transport network that exists on the ground, so the traveled path bends around features and constraints that a straight line ignores.
Water is one common reason for the gap. A direct line on the map may cross water, but an actual trip must use whatever crossing points the road network provides, which adds distance.
Road layout is another reason. Streets and larger roads rarely point exactly from origin to destination, so the path usually includes detours, curves, one-way patterns, and approach roads that make the traveled route longer than the geometric line.
Administrative boundaries can matter too. This venue is in Maryland while the reference city is Washington, D.C., so a real trip crosses jurisdictions. That does not create a fixed mileage by itself, but it is one reason route choice depends on the available network rather than on the simple point-to-point measure.
What this distance tells you, and what it does not
The 7.6-mile figure tells you that Washington, D.C. and MGM National Harbor are geographically close in regional terms. It does not tell you which road route you would take, how long any trip would take on a given day, or what the total on-the-ground mileage would be.
Those missing pieces are not small details; they are the parts most likely to change. Construction, closures, event traffic, pickup points, and your exact starting place inside Washington, D.C. can all alter the practical trip even when the venue's fixed coordinates never change.
How to read the venue's published details
Publicly published reference sources describe MGM National Harbor as a venue in National Harbor, Maryland that opened on December 8, 2016. The same sources document 308 hotel rooms and 135,000 square feet of gaming space at the cited point in time.
Those figures help place the property physically: it is not a small local room but a large built venue with an attached hotel component. As with all property figures, room counts, floor area, ownership, and branding can change over time through renovation, expansion, or sale.
The documented owner here is Vici Properties. Ownership and operation are not the same thing in casino real estate, and venue branding can persist through changes in the underlying property structure.
How this compares with other documented venues near Washington, D.C.
If your real question is whether MGM National Harbor is the nearest documented casino venue to Washington, D.C. in this reference set, the answer is yes within the venues measured here. The file documents 318 venue-to-Washington, D.C. measurements, but it is not a census of every casino venue, so it should not be read as a complete market list.
| Venue | Straight-line miles from Washington, D.C. | Measurement type |
|---|---|---|
| MGM National Harbor | 7.6 | great-circle |
| Maryland Live | 23.4 | great-circle |
| Charles Town | 52.2 | great-circle |
| Harrington | 77.5 | great-circle |
| Bally's Dover | 82.0 | great-circle |
| Delaware Park | 90.8 | great-circle |
| Hollywood Casino | 104.8 | great-circle |
| Ocean Downs | 107.0 | great-circle |
| Valley Forge | 118.6 | great-circle |
| Parx | 138.3 | great-circle |
That comparison still uses straight-line miles only. It does not establish road mileage, trip duration, or convenience, because those depend on the actual route from your own starting point.
What to confirm before you go
Before setting out, confirm the things that change: the route from your exact starting point, parking arrangements, hotel availability if you need a room, venue access rules, and the current hours for any part of the property you plan to use. The authoritative source for those details is the venue's own official site and its guest services contact channel.
If you are comparing this property with another casino, confirm each venue separately rather than relying on one distance figure. Straight-line proximity is stable, but practical access can differ sharply once real roads, bridges, and your own origin point are involved.
If you need a complete and current list of casino venues in the surrounding jurisdictions, use the relevant state, district, provincial, or tribal gaming regulator rather than any partial venue list. This reference set documents measured examples, not a complete census for Washington, D.C. or the wider region.
