The Mid-Atlantic coast is from Virginia up to New York. The term originated with the 13 colonies, where it was one of three primary groupings, alongside New England (Conn, RI, Mass, NH) and the South (Georgia and the Carolinas).
At that time, Mid-Atlantic was being used in the context of the North American continent, rather than the USA, which didn’t yet exist. So if you consider the whole Atlantic coast of North America including Newfoundland and Nova Scotia, it makes more sense.
