Maryland Casinos Map

Maryland has six casinos, and three of them rank among the busiest on the East Coast. This Maryland casinos map shows where each sits, from MGM National Harbor on the Potomac near Washington to Rocky Gap out in the western mountains. Most of the action is packed into the corridor between Washington and Baltimore, where MGM, Live!, and Horseshoe draw the bulk of the state’s play, with three more casinos spread to the northeast, the Eastern Shore, and the far west. The minimum age to gamble is 21.

Where Maryland’s casinos are

Maryland’s casinos follow its population, which means they crowd the center of the state and thin out toward the edges. The heart of the map is the corridor running from Washington up to Baltimore, the densest part of the state, where three large casinos sit within about an hour of one another. MGM National Harbor anchors the southern end on the Potomac at National Harbor, a few minutes from Washington. Live! Casino and Hotel sits in the middle at Hanover, beside the Arundel Mills mall off the Baltimore Washington Parkway. Horseshoe Baltimore holds the northern end, on the south side of downtown Baltimore near the stadiums.

The other three are spread to the corners. Hollywood Perryville sits in the northeast on Interstate 95, the first casino travelers reach coming down from Delaware and Pennsylvania. Ocean Downs is the lone Eastern Shore casino, just inland from Ocean City at a harness racing track. And far to the west, where Maryland narrows into the Appalachians near Cumberland, Rocky Gap is a mountain resort casino unlike anything else in the state. The result is a map weighted heavily toward the middle, with a casino at each far edge for the regions the corridor cannot reach.

§ Maryland casinos by region

The hub’s routing job. Maryland’s casinos fall into three areas, each linking down to its city and casino pages as they come online.

The Washington to Baltimore corridor MGM, Live!, and Horseshoe

The center of gravity for Maryland gaming. MGM National Harbor is the largest and highest grossing casino in the state, a full resort on the Potomac with a hotel tower, a theater, and a long restaurant row, minutes from Washington. Live! Casino and Hotel at Hanover runs the most slot machines in Maryland next to the Arundel Mills mall, halfway up the corridor. Horseshoe Baltimore fills the city end, a Caesars floor by M&T Bank Stadium and Camden Yards. Together these three take the great majority of the state’s casino revenue.

The northeast corner Perryville · on Interstate 95

Hollywood Casino Perryville was the first casino to open in Maryland, in 2010, and it sits right on Interstate 95 in Cecil County. That puts it in front of the heavy traffic running between Baltimore and Philadelphia, and it is the closest Maryland casino for drivers coming down from Delaware and Pennsylvania. It is a smaller floor than the corridor giants, built for convenience off the highway.

The shore and the mountains Ocean Downs and Rocky Gap

The two ends of the state each have a casino of their own. Ocean Downs, just inland from Ocean City, pairs a casino floor with a harness racing track and serves the Eastern Shore and the summer beach crowd. Across the entire width of Maryland, Rocky Gap at Flintstone is a lakeside resort in the western mountains near Cumberland, with a hotel and golf, the only casino in the state that is a destination resort in its own right rather than a floor near a city or a highway.


Casino laws and minimum age in Maryland

Maryland’s casinos arrived by referendum. Voters approved slot machines in 2008 and added live table games in a second vote in 2012, which is why the older properties opened as slots halls and later filled in with table games. The state authorized six casino licenses in all, and all six are now open and run as commercial casinos under the Maryland Lottery and Gaming Control Agency, the same agency that runs the lottery and oversees sports betting. Ocean Downs is tied to a harness track, making it a racino, while the other five are standalone casinos.

The minimum age is 21 at every casino and for sports betting, whether at a retail book or on a phone. The state lottery is open at 18. Sports betting is legal, with retail wagering since December 2021 and online apps since November 2022, but online casino gaming is not legal in Maryland, and the most recent attempt to authorize it was withdrawn in 2026. Hours and rules can change, so confirm the current age and policies with the property before planning around them.

Dated fact Minimum age 21 at every Maryland casino and for sports betting, with the state lottery at 18. Online casino is not legal as of May 2026. Verified May 2026. Recheck before relying on it.


The biggest casinos in Maryland

Two corridor casinos dominate the state. MGM National Harbor, open since 2016, is the highest grossing casino in Maryland and the closest thing the state has to a Las Vegas style resort, with a 135,000 square foot floor, a hotel tower, a 3,000 seat theater, and a row of name restaurants overlooking the Potomac. Live! Casino and Hotel at Hanover is the other heavyweight, holding the most slot machines in the state and its own hotel and event space beside Arundel Mills. Horseshoe Baltimore is a substantial city casino as well. These three carry the bulk of Maryland’s gaming revenue, while the three smaller casinos serve their own corners of the state.

Sports betting and online gaming in Maryland

Maryland legalized sports betting after the casinos were well established, opening retail sportsbooks at the end of 2021 and launching online apps in November 2022. Today you can bet on sports from a phone anywhere in the state or at a book inside the casinos, all for bettors 21 and over and regulated by the Maryland Lottery and Gaming Control Agency. Online casino gaming, the slots and table games you would play on an app, is a different matter and remains illegal in Maryland. A push to authorize it, which would likely require its own voter referendum, was withdrawn in 2026, so for now the casino floor is still the only place to play those games.

Rocky Gap and Ocean Downs, the casinos at the edges

Maryland’s two outlying casinos are worth singling out because they are nothing like the corridor floors. Rocky Gap Casino Resort sits on a mountain lake in a state park near Cumberland, three hours west of Baltimore, pairing a modest casino floor with a resort hotel, a golf course, and the outdoors, a combination with few rivals on the East Coast. Ocean Downs, at the other end of the state, is a harness racing track turned racino just behind the Ocean City beaches, busiest in the summer when the shore fills up. Neither competes with MGM or Live! on scale, but each is the gaming option for a part of Maryland the central casinos do not reach.

Editorial note

Reviewed by the CasinosMap editorial desk. The roster of six casinos, their cities, operators, and the slot and table figures for the larger properties were checked against current authoritative sources rather than prior knowledge, including early 2026 revenue and machine counts from the state regulator. The minimum age, the legal sports betting status, and the fact that online casino remains illegal were verified from current sources. Counts and any largest casino claim are dated and treated as a snapshot.
