Belgium's flag was adopted on 23 January 1831 after independence from the Netherlands. The vertical tricolour deliberately echoes the French Tricolour to signal solidarity with the 1830 revolutions.
The design
The Flag of Belgium is a national emblem rendered in the colours and proportions defined by the country’s flag law. Its official aspect ratio is 13:15, the height-to-length ratio that fixes how the flag should be cut and flown. The colour scheme uses Black, Yellow, Red, with each shade specified to particular Pantone or RGB values for official reproduction.
Colour palette
| Colour | Name | Common symbolism |
|---|---|---|
| Black | Black | May reference the people, ancestral heritage, or the determination to overcome. |
| Yellow | Yellow | Usually denotes wealth, the sun, gold reserves, or a generous spirit. |
| Red | Red | Often signifies courage, sacrifice, revolution or the blood of those who fought for the nation. |

Symbolism & heraldry
Inspired by the French Tricolour but using the colours of the Duchy of Brabant — a black shield with a gold lion clawed in red.
Heraldic elements on the Flag of Belgium — bands, charges, emblems or stars — each carry meaning agreed at the moment of the flag’s adoption. Re-readings happen across generations: a colour or a symbol that began with one meaning often picks up further layers as the country’s history unfolds.
Adoption & history
The current flag was adopted in 1831. Earlier banners flown by Belgium reflected the politics of their day; each redesign typically marked a moment of independence, regime change or constitutional reform. The current flag was chosen, debated and codified through the country’s official channels and is now protected by flag law.
Etiquette & protocol
The Flag of Belgium should be flown with respect: never allowed to touch the ground, never used as drapery for ceremonies it was not made for, and lowered or removed at sundown unless illuminated. When flown alongside other national flags, it takes precedence on home soil and is hoisted first and lowered last. On days of national mourning, the flag is flown at half-mast in line with directives from the head of state. These conventions are common to most nations and are usually written into the flag’s founding statute.
