The flag of Dominica was adopted on 3 November 1978, with some small changes having been made in 1981, 1988, and 1990. The original flag was designed by playwright Alwin Bully in early 1978 as the country prepared for independence.
The flag features the national bird emblem, the sisserou parrot, which also appears on the coat of arms granted on 21 July 1961. This parrot, endemic to Dominica, is an endangered species with a population of only 250–350 individuals.
The green field represents the lush vegetation of the island. The cross represents the Trinity and Christianity, with its three colors symbolizing the natives, the fertile soil, and the pure water. The 10 green five-pointed stars stand for the country's 10 parishes: (St Andrew, St David, St George, St John, St Joseph, St Luke, St Mark, St Patrick, St Paul, and St Peter), while the red disc stands for justice.
The sisserou parrot is sometimes colored either blue or purple (the parrot's actual color). The use of purple makes the flag of Dominica one of only two flags of sovereign states (alongside the flag of Nicaragua) to contain the color.
