Boso of Merseburg was a 10th-century Benedictine monk and the inaugural Bishop of Merseburg. Originally from Bavaria, he served at the court of Otto I before being tasked with the Christianization of the Wends in Saxony. Despite initial resistance from the local population, Boso successfully gained their respect by learning their language to facilitate his preaching. His efforts eventually led to the establishment of several new bishoprics, including Merseburg, Meissen, and Zeitz, which were organized around 967 or 968.
