The village takes its name from 19th-century sawmill businessman John Baker. In 1818, Baker, a native of
Maine, settled in the area, along with several other American families. He was dissatisfied with the official borders, and in 1827 declared the village to be capital of the "
Republic of Madawaska", a self-proclaimed unrecognized sovereign state being part neither of the United States nor of British America (Canada) although comprising portions of both. Baker was subsequently briefly jailed by the British for treason. A US citizen by birth, John Baker continued to live on his settlement as a somewhat reluctant British subject after Baker Brook was officially declared part of New Brunswick. == Demographics ==
