<P> This is a list of the sixteen counties in the U.S. state of Maine . Before statehood , Maine was officially part of the state of Massachusetts and was called the District of Maine . Maine was granted statehood on March 15 , 1820 as part of the Missouri Compromise . Nine of the sixteen counties had their borders defined while Maine was still part of Massachusetts , and hence are older than the state itself . Even after 1820 , the exact location of the northern border of Maine was disputed with Britain , until the question was settled and the northern counties signed their final official form , the Webster - Ashburton Treaty , signed in 1842 . Almost all of Aroostook County was disputed land until the treaty was signed . </P>
