What is the name of the Wikipedia guideline on subject notability?

The Wikipedia guideline on subject notability is called “Notability.” It helps editors decide whether a topic has received enough significant attention in reliable, independent sources to justify a standalone encyclopedia article.

Notability is not the same as fame, popularity, importance, or personal opinion. In general, a subject is considered notable when independent secondary sources have covered it in meaningful detail over time. Those sources help demonstrate that the topic belongs in an encyclopedia rather than existing only as a brief mention, directory entry, or promotional page.

The guideline was introduced in 2006 and later developed into subject-specific guidance for areas such as biographies, organizations, companies, films, and music. Editors still need to cite reliable sources, and meeting a notability guideline does not excuse plagiarism, original research, promotional writing, or other policy violations.

A common mix-up is “Verifiability,” which asks whether claims can be supported by reliable published sources. Notability asks a different question: whether the subject itself merits a separate article. A topic can be verifiable yet not notable enough for its own page.
