The flag of Saint Lucia consists of a cerulean blue field charged with a yellow triangle in front of a white-edged black isosceles triangle. Adopted in 1967 to replace the British Blue Ensign defaced with the arms of the colony, it has been the flag of Saint Lucia since the country became an Associated State of the United Kingdom that year. Although the overall design of the flag has remained unchanged, specific aspects of it have been altered over the years.

The French colonized Saint Lucia in 1635 and subsequently signed a treaty with the local indigenous population 45 years later in 1680. However, the British vied for control with the French, and the island frequently switched hands between the two superpowers. This continued until 1814, when the Treaty of Paris was signed that saw France permanently relinquish Saint Lucia to the British, and it became a crown colony of the United Kingdom within its colonial empire in that same year. During this colonial period of French and British rule, Saint Lucia did not have its own unique colonial flag.

The British finally granted Saint Lucia its own unique coat of arms in August 1939. The escutcheon consisted of a black shield featuring two sticks of bamboo forming a cross, with two Tudor roses symbolising England and two fleurs-de-lis symbolising France occupying the four quadrants. This emblem was utilised to deface the British Blue Ensign in order to form the territory's flag.
