The Appalachian League is a collegiate summer baseball league in the United States. From 1911 to 2020, it was part of affiliated Minor League Baseball. A league champion is determined at the end of each season. Champions have been determined by postseason playoffs or winning the regular season pennant. Currently, the two teams with the highest winning percentages in each of two divisions, East and West, are eligible for the postseason. These teams compete in a single championship game to determine a league champion.
