Green Island is a rocky island near the mouth of Fortune Bay, Newfoundland. It is located about 10 km (6 mi) west of the Burin Peninsula of Newfoundland near Point May, and 10 km (6 mi) east of Saint Pierre Island in the French overseas collectivity of Saint Pierre and Miquelon.

Point May is the most southerly community on the Burin Peninsula in Newfoundland and Labrador with a population of 254 in 2021. It is a Catholic community with a church, town hall, fire hall, softball and soccer field. It is known for its close proximity, 19 km (12 mi), to the French islands of St. Pierre and Miquelon, where the smuggling of liquor and tobacco has been a way of life since before Canada was a country. The tiny Canadian Green Island lies 10 km (6 mi) west of Point May, roughly halfway to St. Pierre.
