Flag of Guyana

A green field serves as the background for two overlapping triangles originating from the hoist side. A large yellow triangle with a white border extends toward the fly, while a smaller red triangle with a black border is positioned directly against the hoist.

Green represents the extensive agricultural and forested lands that define the country's geography. The golden-yellow triangle signifies mineral wealth, while the white border denotes the nation's abundant rivers and water resources. Perseverance is represented by the black border, and the red triangle symbolizes the zeal and dynamic spirit required for national development.

Following a design competition, the national flag was officially adopted upon Guyana's independence from the United Kingdom on May 26, 1966. American vexillologist Whitney Smith submitted the original layout, which was subsequently modified by the British College of Arms to include the black and white fimbriations. Prior to independence, the colony of British Guiana utilized a British Blue Ensign featuring a local badge.
