The Royal Belgian Genealogical and Heraldic Office is a private genealogical and heraldic society in Belgium. It was founded in 1942 as an ASBL and has over a thousand members interested in genealogy and heraldry. While it publishes exclusively in the French language, it covers all regions of Belgium.

For the purposes of this article, heraldry societies are defined as private associations of people who are interested in heraldry. Heraldic authorities, which have been established by reigning monarchs or governments, are dealt with in a separate article.
