Their newest affiliate is the Chattanooga Lookouts of the Southern League, which became the Reds' Double-A club in 2019; they were previously affiliated with Chattanooga from 1988 to 2008.
Geographically, Cincinnati's closest domestic affiliate is the High-A Dayton Dragons of the Midwest League, which are approximately 49 miles (79 km) away.

### 1932–1962

Minor League Baseball operated with five classes (Double-A, Class A, Class B, Class C, and Class D) from 1932 to 1935. Class A1, between Double-A and Class A, was added in 1936. The minors continued to operate with these six levels through 1945. Triple-A was established as the highest classification in 1946, and Class A1 became Double-A, with Class A through D remaining. These six levels continued through 1962. The Pacific Coast League (PCL) was reclassified from Triple-A to Open in 1952 due to the possibility of becoming a third major league. This arrangement ended following the 1957 season when the relocation of the National League's Dodgers and Giants to the West Coast ended any chance of the PCL being promoted.

### 1963–1989

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.

### 2021–present
