In sports, a farm team, farm system, feeder team, feeder club, or nursery club is generally a team or club whose role is to provide experience and training for young players, with an agreement that any successful players can move on to a higher level at a given point, usually in an association with a major-level parent team. This system can be implemented in many ways, both formally and informally.

For instance, business schools are occasionally referred to as "farm clubs" in the world of business.

Although the vast majority of such teams are privately owned and are therefore able to switch affiliation, those players under contract with the affiliated Major League Baseball team are under their exclusive control, and would move to the MLB club's new affiliate. Not all players on a minor league team are under contract with the MLB club; however, the parent club has the exclusive right to "purchase" the contract of a non-contract player at its affiliate. Minor league teams are usually based in smaller cities (although both the New York Yankees and the cross-town rival New York Mets each have a low-level minor-league affiliate actually based elsewhere within New York City), and players who are contracted to them, as opposed to major league players sent down to this level for rehabilitation or other professional-development assignments, are typically paid significantly less than their Major League counterparts. Most major league players start off their careers by working their way up the minor league system, from the lowest (rookie) to the highest (AAA) classification, with the rare exceptions usually being those players signed from Japan's Nippon Professional Baseball. Since the elimination of the Bonus Rule, only a very small number of amateur players have gone directly into the MLB, including John Olerud, Jim Abbott, and Dave Winfield. The process of a player working his way up through the minor leagues is formally referred by most MLB teams as "player development". However, minor
