Fridolin of Säckingen was a 6th-century Irish missionary and Benedictine abbot who worked among the Alamanni. Born in Ireland around 401, he traveled to the region of modern-day Germany, where he established the Säckingen Abbey. Historical records, including a 9th-century inventory, confirm his presence in the area. He is traditionally believed to have died in Bad Säckingen around 538 or 540. As a significant religious figure, he is recognized as a saint in both Catholic and Orthodox traditions.
