Wikipedia:Project namespace

The project namespace or Wikipedia namespace is a namespace consisting of administration pages with information or discussion about Wikipedia. Pages in this namespace will always have the prefix Wikipedia:. They can also be reached by alias WP: or the standard (for any MediaWiki site) prefix Project:. Its namespace number is four (4).


  • Project pages or Wikipedia pages are pages in the Wikipedia and Wikipedia talk namespaces. WikiProject pages, which are included in the Wikipedia namespace, are usually referred to as WikiProject pages to distinguish them from project pages as a whole.
  • Meta – Some people refer to pages in the project namespace as meta pages. However, this can be confusing, because Meta is actually the name of the site dedicated to all Wikimedia projects at
