Madawaska is a town in Aroostook County, Maine, United States. The population was 4,035 at the 2010 census. Madawaska is opposite Edmundston, Madawaska County in New Brunswick, Canada, to which it is connected by the Edmundston-Madawaska Bridge over the Saint John River. Many of its residents speak French; 83.4% of the population speak French at home. Home of a large annual Acadian festival, Madawaska is the northernmost town in New England.HistoryDuring the early colonial period, Madawaska was a meeting place and hunting/fishing area for the Maliseet nation. Later, it was at the center of the bloodless Aroostook War. The final border between the two countries was established with the Webster-Ashburton Treaty of 1842, which gave Maine most of the disputed area, and gave the British a militarily vital connection between the province of Québec and the province of New Brunswick. Unfortunately, many families were left divided after the settlement.
