Italy national under-21 football B team is the Italy national football team that represents Serie B at competitions and is controlled by the Lega B.

Due to sponsorship reasons, the team was credited as Under-21 Serie B TIM until 2010.

Unlike the main team,[clarification needed] the U21 Serie B selects players from Serie B only and was controlled by Lega Calcio (later Lega B) instead of Italian Football Federation (FIGC).

For 2014–2015 season, players born on or after 1 January 1992 are eligible to play.
