意大利青年联赛,简称“意青联”,是一项由意大利足球总会管辖的足球联赛,其级别仅次于意大利足球甲级联赛。联赛主要吸纳意丙和意丁(含以下)的球队,参赛球队数量在60支左右。

该联赛的目标是培养和选拔出优秀的青年足球运动员,为意大利的职业联赛输送人才。参赛球队的平均年龄必须在25岁以下,其中至少有一半的球员必须在21岁以下。此外,球队必须在过去两个赛季中至少有一名球员在意大利职业联赛中出场过。

该联赛分为三个级别:意青联、意青丙和意青丁。其中,意青联冠军将直接升入意甲,而排名最低的意甲球队则会降级到意青联。此外,每个赛季结束后,意青联和意青丙的前两名将直接升入下赛季的意甲和意乙联赛,而排名最低的球队则将被降级到意丁联赛。

该联赛的赛制采用主客场双循环赛制,每支球队需要与其他球队比赛10场。联赛的名次将根据胜负关系决定,胜一场得3分,平局得1分,输球则不得分。此外,该联赛还有升降级制度,确保了比赛的竞争性和吸引力。
