Flag of Saint Kitts and Nevis

The national flag of Saint Kitts and Nevis consists of a yellow-edged black band containing two white stars that divides diagonally from the lower hoist-side corner, with a green upper triangle and red lower triangle. Adopted in 1983 to replace the flag of Saint Christopher-Nevis-Anguilla, it has been the flag of the Federation of Saint Kitts and Nevis since the country gained independence that year.
