Jean-Vincent d'Abbadie de Saint-Castin (1652–1707) was a French military officer serving in Acadia and an Abenaki chief. He is the father of two prominent sons who were also military leaders in Acadia, Bernard-Anselme and Joseph. He is the namesake of the former capital of Acadia, Castine, Maine. He was immortalized by Henry Wadsworth Longfellow (1807–1882) who wrote "The Baron of St. Castine".
