The Milwaukee Brewers farm system consists of seven Minor League Baseball affiliates across the United States and in the Dominican Republic. Four teams are owned by the major league club, while three—the Nashville Sounds, Biloxi Shuckers, and Wisconsin Timber Rattlers—are independently owned.
The Brewers have been affiliated with the High-A Wisconsin Timber Rattlers of the Midwest League since 2009, making it the longest-running active affiliation in the organization among teams not owned by the Brewers. The longest affiliation in franchise history was with the Helena Gold Sox/Brewers, who were the team's Rookie affiliate in the Pioneer League for 32 seasons from 1985 to 2000 and 2002 to 2018. The longest continuous affiliation was the 23-year partnership with the Beloit Brewers/Snappers of the Class A Midwest League from 1982 to 2004. Their newest affiliate is the Wilson Warbirds of the Carolina League, which became the Brewers' Single-A club in 2026.
A total of 31 league championships have been won by 20 different teams during their partnerships with Milwaukee. Of these, the Arizona Complex League Brewers of the Rookie Arizona Complex League (ACL) have won five titles, more than any other team. The Stockton Ports, a Class A-Advanced affiliate in the California League, won four titles, more than any other independently owned club. Additionally, two Triple-A teams each won the championship of their classification. The Denver Zephyrs of the American Association won the 1991 Triple-A Classic, and the International League's Indianapolis Indians won the 2000 Triple-A World Series.
Geographically, Milwaukee's closest domestic affiliate is the Wisconsin Timber Rattlers, which are approximately away. Milwaukee's furthest domestic affiliate is the ACL Brewers some away.

1968–1989 Prior to the 1963 season, Major League Baseball (MLB) initiated a reorganization of Minor League Baseball that resulted in a reduction from six classes to four (Triple-A, Double-A, Class A, and Rookie) in response to the general decline of the minors throughout the 1950s and early-1960s when leagues and teams folded due to shrinking attendance caused by baseball fans' preference for staying at home to watch MLB games on television. The only change made within the next 27 years was Class A being subdivided for the first time to form Class A Short Season in 1966.

1990–2020 Minor League Baseball operated with six classes from 1990 to 2020. In 1990, the Class A level was subdivided for a second time with the creation of Class A-Advanced. The Rookie level consisted of domestic and foreign circuits. The Brewers did not field a Class A Short Season team during this period.

2021–present The current structure of Minor League Baseball is the result of an overall contraction of the system beginning with the 2021 season. Class A was reduced to two levels: High-A and Low-A. Low-A was reclassified as Single-A in 2022.
