A ballpark, or baseball park, is a type of sports venue where baseball is played. The playing field is divided into two field sections called the infield and the outfield. The infield is an area whose dimensions are rigidly defined in part based on the placement of bases, and the outfield is where dimensions can vary widely from ballpark to ballpark. A larger ballpark may also be called a baseball stadium because it shares characteristics of other stadiums.

American Family Field is a retractable roof stadium in Milwaukee, Wisconsin. Located southwest of the intersection of Interstate 94 and Brewers Boulevard, it is the home ballpark of Major League Baseball's Milwaukee Brewers. It opened in 2001 as a replacement for Milwaukee County Stadium. The stadium was previously called Miller Park as part of a $40 million naming rights deal with Miller Brewing Company, which expired at the end of 2020.
