Séra Eiríkur Magnússon í Vogsósum (c.1637(?)/1638–1716), was an Icelandic priest and Galdrmaster. While he was a real person, he has been the subject of many folk tales because of his interest in and study in witchcraft. He is known in Icelandic folklore, where there are many folktales about his alleged magical abilities. He owned the farm Vogsósar, and was the vicar of Selvog church in the parish of Selvogur from 1677–1716. Some tales with him as the hero center on his magical duels with Stokkseyrar-Dísa. As a child he attended the Cathedral School at Skálholt to about 1658 and was ordained in 1668 by Bishop Brynjólfur Sveinsson as curate of Arnarboeli. He became the parish priest of Vogsósar in 1667.
