2012年至2013年德国足球乙级联赛是第39届德国足球乙级联赛。赛季于2012年8月3日开始，至2013年5月19日结束，其中2012年12月15日至2013年2月2日为冬歇期。在本届德乙最终名列冠军和亚军的俱乐部将有资格参加2013年至2014年德国足球甲级联赛。而本届德乙排名第3位的俱乐部与本届德甲排名第16位的俱乐部、以及本届德乙排名第16位的俱乐部与本届德丙排名第3位的俱乐部会进行两场附加赛，以确定最后的升、降级名额。

参赛球队
在2011-12赛季结束后，菲尔特与法兰克福直接升入2012-13赛季德甲。菲尔特是在时隔15年后离开德乙，并首次在顶级联赛中亮相，而法兰克福只是在德乙完成了一个客串赛季便重返德甲。两支升级球队留下的空缺名额由科隆和凯泽斯劳滕填补，他们是在2011-12赛季德甲结束后降级。其中科隆是连续4年停留于德甲后重返德乙，而凯泽斯劳滕则是时隔2年便回到德乙。

在积分榜的另一端，亚琛和汉莎罗斯托克直接降至2012-13赛季德丙。亚琛是自1998-99赛季以来首次跌落第三级别联赛，而罗斯托克则结束了他们在德乙的客串赛季。两支降级球队留下的名额空缺由2011-12赛季德丙的冠军桑德豪森和亚军阿伦填补，这是两支球队在这一级别联赛的首次亮相。

另外2个参赛名额则通过两回合制的附加赛决出。在上季德甲第16名柏林赫塔和上季德乙第3名杜塞尔多夫之间的比赛以总比分3比4结束。因此，杜塞尔多夫结束了在德乙为期三年的魔咒，并在低级别联赛沉沦15年后重返德甲；与此相反，柏林赫塔则结束了在顶级联赛的客串亮相而重返德乙。然而，这个决定是临时性的，因为柏林赫塔对双方的第二回合比分提出上诉，指控他们的失败是由现场发生的多起人群骚乱所造成。

另一方面，在上季德乙第16名卡尔斯鲁厄和上季德丙第3名雅恩雷根斯堡之间的比赛以总比分3比3告终，雷根斯堡凭借客场进球制规则而实现升级。这支巴伐利亚球队是时隔8年重返德乙，卡尔斯鲁厄则结束了为期三年的魔咒，自2000-01赛季以来首次降入第三级别联赛。

体育场及方位
有5支球队扩大了其主场的座位容量。随着成功实现升级，阿伦、雅恩雷根斯堡和桑德豪森分别将主场容量提高至12,500人、13,251人和12,100人 。另一方面，圣保利的在整个秋季都在进行入口非终点直道的重建。而慕尼黑1860所在的安联球场也得益于合作商户和同城死敌拜仁慕尼黑的扩建，在2012年8月下旬将场地总容量提升至71,000人。

另外3支球队的主场容量则由小幅下降，这是由于布伦瑞克、法兰克福FSV和柏林联盟都在对他们的场地站席进行改造。因此在改造过程中，布伦瑞克将能够承载22,100名观众，而法兰克福FSV和柏林联盟则可分别承载10,470名和16,750名观众
