Tagino (died 9 June 1012) was the third Archbishop of Magdeburg from 1004 until his death. Tagino was a chaplain of Henry II, Duke of Bavaria, when, in 995, the See of Regensburg became vacant. He was the duke's candidate for bishop, as well as the candidate of late bishop Saint Wolfgang, and he was elected by the congregation; but the Emperor Otto III appointed his own chaplain Gebhard and instead adopted Tagino into his own royal chaplaincy. Some strife ensued between the duke and the emperor concerning this event.
