The flag of Wallonia represents the Walloon Region and the French Community of Belgium.

Designed in 1913, the flag depicts a red rooster (known as the cok walon in Walloon) on a yellow field.

The rooster represents Walloon adherence to French culture as well as their Gallo-Roman origins.

The rooster was created in 1913, based on a painting by Pierre Paulus,[2] but choosing the colors of Liège was not obvious from the start.

In the beginning, the image of a rooster on the French tricolor was often used, this design survived as a flag of Rattachism.
