The District of Maine was the governmental designation for what is now the U.S. state of Maine from October 25, 1780 to March 15, 1820, when it was admitted to the Union as the 23rd state. The district was a part of the Commonwealth of Massachusetts and before American independence had been part of the British province of Massachusetts Bay.
