The Pabst Brewery Complex, on a hill northwest of the downtown of Milwaukee, Wisconsin, is the former brewery of the Pabst Brewing Company, where the company innovated to improve their beer and increase production until in 1892 it was the largest brewer of lager in the world. In 2003 the complex was listed on the National Register of Historic Places.

The Pabst Brewing Company is an American company that dates its origins to a brewing company founded in 1844 by Jacob Best and was, by 1889, named after Frederick Pabst. It is currently a holding company which contracts the brewing of over two dozen brands of beer and malt liquor: these include its own flagship Pabst Blue Ribbon, as well as brands from many now-defunct breweries.
