 The Betterton Historic District consists of a collection of vernacular Victorian era-style wooden frame resort structures.  The district includes many of the homes, hotels and cottages built to accommodate steamboat passengers in the late 19th and early 20th centuries. Notable buildings within the district include the hotels and boarding homes which catered to the steamboat passengers, several churches, and summer cottages, dating from the golden age of the passenger steamboats on the Chesapeake Bay.
 It was added to the National Register of Historic Places, (maintained by the National Park Service of the United States Department of the Interior) in 1984.
 The recorded history of Betterton dates back to the 17th century. The Fishall Patent was granted in 1664, later becoming known as Fish Hall. The house located at 104 Ericsson Avenue contains foundation bricks dating back to 1698. In 1715, Edward Crew leased Fish Hall and the name was changed to Crews Landing.
For the next 100 years, Crews Landing was a small fishing village and then later a port for the waterborne transport of local farm produce to urban markets. In 1851, Richard Townsend Turner (a Quaker) named the town “Betterton” after the family of his wife Elizabeth Betterton. The Turner pier, and later the Ericsson pier, provided access to the town for the shipping trade. Eventually townspeople rented out rooms to the travelers, salesmen, and shippers attracted to the beach. Mr. Turner built the Rigbie Hotel (demolished in August 1986) and Mr. Crownhart built the Belmont Hotel (destroyed by fire in 1956). These were joined by such lodging establishments as the Betterton, the Chesapeake, the Country Cousin, the Southern, and many others.
 Steamboat traffic from downtown Baltimore's "The Basin" (now Inner Harbor) and Philadelphia on the excursion cruises like the Old Bay Line (Baltimore Steam Packet Company, 1840-1962) and the competing Ericsson Line (and others, such as the Wilson Line later) brought the visitors and vacationers from the Middle Atlantic cities. The Ericsson Line was named after John Ericsson (1803-1889), the Swedish-American inventor of the "screw propeller" (and of Civil War revolutionary naval Ironclad warships) to more speedily and efficiently power ships. It was this invention that allowed steamboats to be built with narrow enough beam to allow them to traverse the recently opened Chesapeake and Delaware Canal then only 25 feet wide (before it was later widened and improved), connecting the upper Chesapeake with the Delaware River and Bay. Betterton was an easy and natural stop for boats using the canal and the explosion in steamboat traffic along the American East Coast brought growth and prosperity to Betterton. For some time before the turn of the 20th century, there were 11 scheduled steamboat landings daily at Betterton's piers. The boom period for Betterton is generally thought to be from 1918 to 1930, when increasing numbers of restaurants, taverns, dance halls, bowling alleys, and amusement arcades all helped create the bayside town's pleasure resort image.
 It eventually declined along with neighboring competing Tolchester and Tolchester Beach after the 1949-1952 construction of the Chesapeake Bay Bridge from Annapolis to Kent Island and increasing automobile traffic over improved U.S. Routes and Interstate Highways systems in following decades to North Atlantic Ocean beaches and growing resort towns there like Ocean City, Maryland and Rehoboth Beach, Delaware

 Betterton is governed by a mayor and a town council with four members.  Town council meetings are held on the second and fourth Tuesday of every month at 7:00 pm in the town hall.  The town hall is located in the Betterton Community Center, a former Catholic church refurbished as town offices and a museum, on Main Street.
 The primary means of travel to and from Betterton is by road. The only state highway serving the town is Maryland Route 292, which has its northern terminus at the north end of town.
 Betterton Beach is located at the foot of Main Street.  The beach has 300 feet (91 m) of frontage for swimming.  The water is generally free of sea nettles because the water is not very salty. The beach has public restrooms (seasonal), a boardwalk, a fishing jetty, a public landing, and reasonable parking.  A picnic pavilion is nearby.
