The coat of arms of Saint-Barthélemy is a shield divided into three horizontal stripes, three gold fleur-de-lises on blue, above a white Maltese cross on red, over three gold crowns on blue, and reads "Ouanalao". On a white background, it serves as the unofficial flag of Saint Barthélemy.
The flag of Saint Barthélemy is the French tricolor. This is because Saint Barthélemy is a self-governing overseas collectivity of France. An unofficial flag of Saint-Barthélemy consisting of the island's coat of arms centered on a white field is also used on the island.
