Erchanbert of Freising was a 9th-century Catholic bishop who led the diocese of Freising. Born into the noble Bavarian Huosi family, he received an education at the cathedral school under the guidance of his uncle, Bishop Gitto. Following Gitto's death, Erchanbert assumed the episcopal seat in 836. He was a significant political and religious figure, participating in the Treaty of Verdun in 843 and managing the wealthy Kempten Abbey as an abbot under the authority of King Louis the German.
