Listed below are each of the active sports leagues in Minor League Baseball, with linked articles containing rosters for each active team in the league.

As with nearly all North American professional team sports, there are limits to the roster sizes of minor-league teams, which vary by classification level. Major League Baseball-affiliated teams are limited in how many players they may place on their active rosters, except for some "rookie" leagues. At lower classification levels, there are restrictions on how much prior professional experience players on the roster may have.

While a team's active roster consists of players eligible to compete for the team in games, a team's reserve roster consists of players on the injured list, those who are restricted or suspended, or who are otherwise temporarily inactive.[1] Major league players on rehabilitation assignments do not count against active roster limits.[2]

As of the 2021 season, the following limits are used:

Level Active roster size[3]: 10–11  Player restrictions[3]: 100 
Triple-A 28 players no restrictions
Double-A 28 players no restrictions
