The imperial amazon is endemic to the Caribbean island nation of Dominica in the Lesser Antilles where it inhabits mountain forest areas above 2,100 ft (625 m). It is the island's national bird and also appears on the country's flag. The species frequently occurs in the Morne Diablotins in northern Dominica, especially the upper Picard River Valley on the northwest side of the mountain. A small population has been reintroduced in the Morne Trois Pitons National Park.
