Which state is not considered part of the Appalachian region?

Kansas is not considered part of the Appalachian region because it lies geographically west of the Appalachian Mountains, which primarily extend through the eastern United States. The Appalachian region includes states such as Kentucky and Virginia, where the mountain range and its cultural influences are prominent. Alabama, while located in the southern United States, also has parts of the Appalachian Mountains within its borders. Kansas, being in the Great Plains region, is distinctively separate from the Appalachian geographic and cultural characteristics, making it the answer that does not fit within the context of the question.
