Marblehead is a coastal New England town in Essex County, Massachusetts, United States, along the North Shore. Its population was 20,441 at the 2020 census. The town lies on a small peninsula that extends into the northern part of Massachusetts Bay. Attached to the town is a near island, known as Marblehead Neck, connected to the mainland by a narrow isthmus. Marblehead Harbor, protected by shallow shoals and rocks from the open sea, lies between the mainland and the Neck. Beside the Marblehead town center, two other villages lie within the town: the Old Town, which was the original town center, and Clifton, which lies along the border with the neighboring town of Swampscott.
