The ITF Men's World Tennis Tour (formerly ITF Men's Circuit) is a series of professional tennis tournaments held around the world that are organized by the International Tennis Federation. The tour represents the lowest rung of the men's professional tennis ladder. ITF tournaments are incorporated into the ATP rankings, enabling young professionals to progress on to the ATP Challenger Tour and ultimately the full ATP Tour. Nearly every professional male player has spent some time on the ITF Men's World Tennis Tour.
