Mannanarie is a rural locality in the Mid North region of South Australia, situated in the Northern Areas Council. It was established in April 2001, when boundaries were formalised for the “long established local name”. It comprises most of the cadastral Hundred of Mannanarie, apart from a northern section which lies in Tarcowie and Yatina. The name stems from an Aboriginal word, “manangari”, meaning “good string or cord”, stemming from a local native plant useful for string making.
