WorldHeritage.wiki is a global digital initiative focused on documenting, preserving, and celebrating humanity’s shared heritage. It brings cultural, natural, and philanthropic heritage together in a publicly accessible knowledge repository, aiming to make research and information available to communities, scholars, and future generations. The platform covers cultural heritage such as historic sites, architecture, archaeology, arts, languages, festivals, and museum collections; natural heritage including ecosystems, biodiversity, geological features, and conservation projects; and philanthropic heritage, highlighting people and organizations advancing cultural, environmental, educational, and community welfare initiatives.

WorldHeritage.wiki offers heritage documentation and research resources, multimedia storytelling, and opportunities for community participation. It says it draws on resources from institutions and platforms including UNESCO, the World Heritage Centre, World History, Wikipedia, and Google, and collaborates with governments, cultural institutions, researchers, and global partners. Its World Heritage Secretariat also invites nominations for Heritage Site Recognition, covering cultural and natural sites as well as philanthropic initiatives. Governments, organizations, communities, experts, and individuals may submit documented nominations or share information about significant heritage by email.
