The Council of Heraldry and Vexillology (French: Conseil d’héraldique et de vexillologie) is the Heraldic authority for the French-speaking Community of Belgium.

It is the institution that advises the Government of the French-speaking Community on all matters concerning civic, personal, and familial arms and flags.

Grants of arms from the Council are published in the Belgian official journal.

[2][3] Its first purpose was to give the French Community its arms, to recognise the arms, seals and flags of cities and municipalities (communes)[4] issued from fusions[5] and to publish from its work, an armorial of the French Community of Belgium.

[7][8] This mission was previously the role of the Royal Belgian Genealogical and Heraldic Office.
