Bobbio Abbey is a monastery founded by Irish Saint Columbanus in 614, around which later grew up the town of Bobbio, in the province of Piacenza, Emilia-Romagna, Italy. It is dedicated to Saint Columbanus. It was famous as a centre of resistance to Arianism and as one of the greatest libraries in the Middle Ages. The abbey was dissolved under the French administration in 1803, although many of the buildings remain in other uses.

Columbanus was an Irish missionary notable for founding a number of monasteries after 590 in the Frankish and Lombard kingdoms, most notably Luxeuil Abbey in present-day France and Bobbio Abbey in present-day Italy.
