Category:Hidden categories

Hidden categories aren't shown in the list of categories at the bottom of the page, unless the "Show hidden categories" preference is checked.

A category is marked as hidden by putting the  magic word on the category page. It is automatically added to this category.

Maintenance categories should generally be here as they're only useful to editors.
