The national flag of Belgium (Dutch: vlag van België, French: drapeau de la Belgique, German: Flagge Belgiens) is a tricolour consisting of three equal vertical bands displaying the national colours of Belgium: black, yellow, and red.

The national flag of Belgium was adopted on January 23, 1831, shortly after gaining independence from the Netherlands. The flag is a tricolor of three equal, vertical bands of black, yellow and red. The black is nearest the flag pole, on the hoist or left side, then the yellow in the middle and red is on the fly end or right.

The national flag of Belgium consists of three vertical stripes in black, yellow and red (from left to right). The format of three stripes was inspired by the flag of France. The colors were taken from the Dukes of Brabant (region between Belgium and Holland).

The Belgian flag is tricolor with a design consisting of three equal bands of black, yellow, and red in a vertical manner. These colors are symbolic and were taken from the cockade of the Duchy of Brabant. The heraldry flag consisted of a yellow lion with a red tongue and claws on a black background.

After Belgium became an independent country in 1830, it was necessary to choose a flag for the new country. Our national flag has three colours: black, yellow and red. These are the colours of the heraldry of the Duke of Brabant: a yellow lion, with red claws and a red tongue on a black background.
