The post office established here in 1911 was named by the area's settlers who had come from Nova Scotia. Acadia, or Acadie in French, was the name given by France to all New World Atlantic Seaboard possessions, that included Nova Scotia, New Brunswick, and parts of Quebec and Maine from the early 17th century to the mid-18th century. The name is possibly derived from the Abnaki, Malecite or Micmac language, and is translated as "nothing here."
