Atlantic Canada, also called the Atlantic provinces, is the region of Eastern Canada comprising four provinces: New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. As of 2021, the landmass of the four Atlantic provinces was approximately 488,000 km² (188,000 sq mi), and had a population of over 2.4 million people. The term Atlantic Canada was popularized following the admission of Newfoundland as a Canadian province in 1949. The province of Newfoundland and Labrador is not included in the Maritimes, another significant regional term, but is included in Atlantic Canada.
