Vital articles is a list of subjects for which Wikipedia should have corresponding high-quality articles. It serves as a centralized watchlist to track the status of Wikipedia's most essential articles. This is one of eleven Level 4 sub-lists of ten thousand articles and is currently under construction.

Articles are labelled as:

• Featured articles
• Former featured articles
• A-class articles
• Good articles
• Delisted good articles
• B-class articles
• C-class articles
• Start-class articles
• Stub-class articles
• A full list is at Template:Icon/doc

These symbols are updated manually and may be out of date; you are encouraged to fix any errors you discover.

This list is tailored to the English-language Wikipedia. There is also a list of one thousand articles considered vital to Wikipedias of all languages.

For more information on this list and the process for adding articles (please see the Frequently Asked Questions (FAQ) page.
