Third Coast is a term to describe the highly
urbanized stretch of U.S. cities and large towns along the
Great Lakes shoreline. This area is generally considered to be bordered by Southeast Wisconsin on the West and Upstate New York on the East.
It is referred to as the Third Coast because politically and socially, it aligns more with coastal states than the rest of so-called "
Middle America." It also shares a lot of physical similarities (such as beaches) which are commonly thought to only exist on the coasts.
Recently, residents of Chicago have tried to claim their city alone is synonymous with Third Coast. However, it actually refers to the entire Great Lakes region as there are a number of entities in the business and entertainment world outside of Chicago (especially in Wisconsin, Michigan and Ohio) that identify themselves as "Third Coast."
Some of the major cities in this region are Buffalo, Chicago, Cleveland, Detroit, Milwaukee and Pittsburgh.
(Please note that similar to how Philadelphia is considered East Coast even though it's not actually on the ocean, a city does not actually have to be on the Great Lakes to be considered part of the Third Coast.)
