WWE utilizes a farm system that allows inexperienced wrestlers to develop their skills and gain in ring experience in smaller, often regional, promotions before they are called up to compete in front of a global/national audience. The following is a list of WWE Development Territories.

In addition, smaller companies such as Ring of Honor, Combat Zone Wrestling, Chikara or the now-defunct Extreme Championship Wrestling can act as unofficial feeder leagues, seasoning wrestlers until a larger company offers them a contract.
