Berlin [bʌrlɪn] is a town in Worcester County, Maryland, United States which includes its own historical Berlin Commercial District. The population was 4,485 at the 2010 census, and has since grown in population. It is part of the Salisbury, Maryland-Delaware Metropolitan Statistical Area.

The town of Berlin lies over land that was originally the 300-acre Burley Plantation, patented by William Tomkins in 1677. With the development of ancient Native American migratory and hunting trails into colonial highways, the Burley Plantation became a crossroads of a post road leading to Philadelphia (today's Main Street) and the Sinepuxent Road. Berlin developed in the early-19th century at this crossroads, where a tavern, blacksmith shop, and livery were among the first established businesses in the new town. Regional tradition asserts that the pronunciation of the town's name, "Burl'in" with emphasis on the first syllable, stems from the "Burley Inn", the early tavern that stood at the crossroads of the Philadelphia Post and Sinepuxent Roads.

Soon after the Civil War, Berlin was incorporated as a town in 1868 and a period of significant growth ensued. Within the next decade, the arrival of the Delaware, Maryland, and Virginia Railroad made Berlin into a commercial center for upper Worcester County. After a fire in 1895 leveled a significant portion of the central commercial district, Victorian structures displaying elements of Queen Anne, Italianate, and Second Empire styles were erected along Main Street. The rise of nearby Ocean City as a tourist destination in the early-twentieth century also aided Berlin's economy by making the town a convenient rest stop. Just to the north of the town center of Berlin is Ocean Pines, Maryland, a waterfront census-designated place (CDP) that shares the same ZIP code as Berlin.

Since the late 1980s, the town has undergone considerable revitalization of its historic downtown commercial district and adjacent residential areas. Berlin's historic residential areas feature nearly two centuries of architectural heritage from three distinct periods: Federal, Victorian, and 20th Century. Forty-seven of these structures have been noted in the National Register of Historic Places and the Berlin Commercial District. Berlin has also been designated as a "Main Street Community" by the State of Maryland in recognition of its revitalization progress.

In addition to the Berlin Commercial District, the Buckingham Archeological Site, Burley Manor, Caleb's Discovery, Fassitt House, Genesar, Henry's Grove, Merry Sherwood and Williams Grove are listed on the National Register of Historic Places.

Berlin is located at 38°20'N 75°13'W (38.3311,-75.2140).

According to the United States Census Bureau, the town has a total area of 3.15 square miles (8.16 km), all land.

The Berlin Electric Utility Department provides electricity to Berlin, serving 3,500 customers. The electric utility operates a power plant along Williams Street in Berlin that generates some of its electricity while it also purchases power from outside sources. On September 19, 2006, residents of Berlin voted in favor of selling the town's electric department to Choptank Electric Cooperative, a move supported by the mayor and town council because of the utility's debt and high rates but opposed by the Berlin Utility Commission because of the feared loss of revenue. Under this arrangement, Choptank Electric Cooperative would have taken over the distribution system while Old Dominion Electric Cooperative would have taken over the town's power plant. The sale fell through in 2007 after Old Dominion Electric Cooperative backed out of the deal because it felt the town's power plant did not meet the environmental standard for a residential area; Choptank Electric Cooperative soon backed out too.
