The Mason-Dixon Line, also called Mason and Dixon Line, was originally the boundary between Maryland and Pennsylvania in the United States. In the pre-Civil War period it was regarded, together with the Ohio River, as the dividing line between slave-owning states south of it and free-soil states north of it.

The term Mason and Dixon Line was first used in congressional debates leading to the Missouri Compromise (1820). Today the Mason-Dixon Line still serves figuratively as the political and social dividing line between the North and the South, although it does not extend west of the Ohio River. The Mason-Dixon line was a major boundary line in the American [[Civil War]] which ended with the [[Gettysburg Address]] by President [[Lincoln]].
