The national flag of Guinea (drapeau national de la Guinée) was adopted on 10 November 1958, with the publication of the country's first Constitution.

[1][2] The colors of the flag were adapted from those of the Rassemblement Démocratique Africain, the dominant movement at the time of independence.

The colors were in turn derived from those of the flag of Ghana, which had first adopted them in 1957.

According to Sékou Touré, first President of Guinea, the three colors of the flag represent the following: red symbolizes the blood of anti-colonialist martyrs, the labor of the working classes, and the wish for progress; yellow represents Guinean gold, as well as the sun, which is "the source of energy, generosity and equality for all men to which he gives light equally"; and green represents the country's vegetation, continued prosperity arising from its natural resources, and the historically difficult life of the Guinean masses who live in the countryside.

[3] In keeping with other flags in the region, the Pan-African movement's colors of red, yellow, and green are used.
