The Tampa Bay Rays 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 Florida Complex League Rays and two Dominican Summer League Rays squads—are owned by the major league club.
The Rays have been affiliated with the Triple-A Durham Bulls of the International League since 1998, making it the longest-running affiliation in the organization among teams not owned by the Rays. Their newest affiliate is the Charleston RiverDogs of the Carolina League, which became the Rays' Single-A club in 2021.
Geographically, Tampa Bay's closest domestic affiliate is the Rookie Florida Complex League Rays, which are approximately away. Tampa Bay's furthest domestic affiliate is the High-A Bowling Green Hot Rods of the Midwest League some away.

Key
1996–2020
Minor League Baseball operated with six classes (Triple-A, Double-A, Class A-Advanced, Class A, Class A Short Season, and Rookie) from 1996 to 2020. 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.
