Adalbert of Magdeburg, sometimes incorrectly shortened to "Albert" (c. 910 - 20 June 981), and known as the Apostle of the Slavs, was the first Archbishop of Magdeburg (from 968) and a successful missionary to the Polabian Slavs to the east of what is contemporarily Germany. He was later canonised and his liturgical feast day was assigned as 20 June.
