The Flag of Saint Lucia was adopted on March 1, 1967. The exact design has varied. The current flag is blue, with a gold isosceles triangle below a black arrowhead; the upper edges of the arrowhead have a white border.

The blue color stands for the blue sky and blue ocean that surround the island, and for fidelity. Gold stands for sunshine and prosperity. The black and white portions symbolize racial harmony, although the majority of black shows the dominant influence of black culture over European culture. The triangle parts of the design are intended to evoke the Pitons, the island's two large peaks that rise from the ocean and are recognized symbols of the island.
