Columbanus (, 543 – 21 November 615), also known as St. Columban, was an Irish missionary notable for founding a number of monasteries on the European continent from around 590 in the Frankish and Lombard kingdoms, most notably Luxeuil Abbey in present-day France and Bobbio Abbey in present-day Italy. He is remembered as a key figure in the Hiberno-Scottish mission, or Irish missionary activity in early medieval Europe.
