Placentia Bay (French: Baie de Plaisance) is a body of water on the southeast coast of Newfoundland, Canada.
Fishing grounds in the bay were used by native people long before the first European fishermen arrived in the 16th century.
The town and nearby Castle Hill are national historic sites.
English settlement followed in the bay and today the main communities are Burin, Marystown, and Placentia.
