Waldoboro is a town in Lincoln County, Maine, in the United States. Waldoboro is a picturesque fishing and resort town. It was part of the Waldo Patent purchased about 1720 by General Samuel Waldo of Boston. First called Broad Bay, the village was settled between 17331740, but thereupon suffered a devastating attack by Indians allied with New France during King George's War. Houses were burned and inhabitants killed or carried away as captives. Survivors fled to the nearby settlements of St. George or Pemaquid. But peace returned with the 1748 Treaty of Aix-la-Chapelle.
