Heraldry of the World (HOTW or Heraldry-wiki.com; formerly NGW, for the original Dutch name Nederlandse GemeenteWapens (Dutch civic heraldry)) is an Internet-based heraldic resource. Its principal project is the Internet's largest website devoted to civic heraldry, containing comprehensive information about all kinds of coats of arms of (local) government authorities, including countries, states, provinces, colonies, regions, districts, cities, towns, and municipalities worldwide. In addition to these the site also has a large literature and reference list and a section on heraldic collector items. Since 2017 also Corporate, Institutional, Military and Ecclesiastical heraldry has been added. Since 2018 the site has a new URL as heraldry-wiki.com.
