Saint Lucia’s flag (1 March 1967; retained 1979) is cerulean blue with a gold isosceles triangle before a black arrowhead edged in white. Blue evokes sea and sky; gold sunshine and prosperity; black and white the harmonious peoples and the Pitons. Minor refinements aside, the design endures; strict protocol applies.
Adopted with associated statehood on 1 March 1967 and retained at independence in 1979, Saint Lucia’s flag arose from a public contest won by artist Dunstan St Omer. Its abstract geometry distils landscape and society into a concise emblem.
The field is cerulean blue for the Caribbean Sea and sky. Centred is a gold isosceles triangle signifying sunshine, prosperity, and aspiration. In front of it stands a black arrowhead edged in white, evoking the twin volcanic Pitons and the harmonious relationship of Saint Lucia’s black and white populations within a wider mixed‑heritage society. Over time, official guidance has adjusted blue shades and triangle proportions, but the core composition persists.
Protocols regulate respectful handling, daily display on public buildings, half‑masting for mourning, and dignified retirement. Maritime practice uses appropriate ensigns based on the national flag.
