Miller Brewing is a large American beermaker based in Milwaukee. It was founded in 1855 by Frederic Miller when he purchased the small Plank-Road Brewery. The brewery's location in the Menomonee Valley provided easy access to raw materials produced on nearby farms. It also has a brewery in Butler County, Ohio's St. Clair Township.

It was acquired by South African Breweries from Philip Morris on May 30, 2002, to form SABMiller for $3.6 billion worth of stock and $2 billion in debt, with Philip Morris retaining a 36% share, with voting rights of 24.99%.

Miller Brewing owns breweries in Albany, Georgia; Eden, North Carolina; Fort Worth, Texas; Irwindale, California; Milwaukee, Wisconsin and Trenton, Ohio.
