List of Texas Rangers minor league affiliates

The Texas Rangers farm system consists of seven Minor League Baseball affiliates across the United States and in the Dominican Republic. Four teams are independently owned, while three—the Arizona Complex League Rangers and two Dominican Summer League Rangers squads—are owned by the major league club.

The Rangers have been affiliated with the Double-A Frisco RoughRiders of the Texas League since 2003, making it the longest-running active affiliation in the organization among teams not owned by the Rangers. The longest affiliation in team history was the 28-year relationship with the Triple-A American Association/Pacific Coast League's Oklahoma City 89ers/RedHawks from 1983 to 2010. From 2011 through 2018, the Rangers were affiliated with the Round Rock Express of the Pacific Coast League as their Triple-A club. After a brief alignment with the Nashville Sounds (2019–2020), the Rangers resumed their affiliation with the Round Rock Express in 2021.

Geographically, Texas' closest domestic affiliate is the Frisco RoughRiders, which are approximately 28 mi away. Texas' furthest domestic affiliate is the Single-A Down East Wood Ducks of the Carolina League some 1129 mi away.

1961–1962
Minor League Baseball operated with six classes (Triple-A, Double-A, Class A, Class B, Class C, and Class D) from 1961 to 1962.

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.

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.

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.
