|This page documents an English Wikipedia editing guideline.|
Except in the main namespace (article namespace), where the subpage feature has been disabled in the English Wikipedia, subpages are pages separated with a "/" (a slash) from their 'parent' page.
Making a new [[link]] that begins with a / (slash) is the common way to start a subpage. The page to which this link points is considered "subordinate" to its host page, and is titled and linked as [[Parentpage/Subpage]]. It is possible to create a subpage of a subpage (or a sub-subpage). At the top of each subpage or sub-subpage, you can find a backlink (a.k.a. breadcrumb) to the higher levels of the page.

The "All pages with prefix" report from Special:PrefixIndex shows subpages.

The "Search" report from Special:Search similarly uses a prefix search parameter to show subpages. For example: .
Comparing the two:
To keep an active display of subpages, see ((list subpages)). To keep a link to an "All pages..." report, use ((subpages)) or [[Special:PrefixIndex]]. To keep a link to a "Search" report, use a ((search link)).
Outside of a single page name, there is no direct method for finding subpages. Standard subpagenames are searchable using the intitle parameter.
The MediaWiki software (which runs Wikipedia) supports selectively allowing or disallowing the creation of subpages in various namespaces.
The following namespaces in English Wikipedia do not have the subpage feature:
However, the corresponding talk namespaces for the above spaces do allow subpages.
All other namespaces allow subpages. You can create a subpage simply by linking to the name of the subpage, prefixed with a slash (e.g. [[/Archive]]).
Some topics have a slash in the name, and should be named accordingly—e.g. OS/2 or Providence/Stoughton Line. Care should be taken with the corresponding talk pages, though, as subpages are enabled in talk space—for example, Talk:OS/2 is treated by the software as a subpage of Talk:OS.
Subpages were originally used on Wikipedia to differentiate between subjects to create topical hierarchies of articles, but this proved unworkable because articles tend to belong in more than one hierarchy. The present system of disambiguation was adopted instead, and the Wikipedia:Do not use subpages policy had to be rigorously enforced and retroactively applied. Since 2004, the category system has supported hierarchical organization while still allowing an article to belong to multiple categories.

Note that older discussions of subpages are generally concerned with articles named as subpages of other articles; this is no longer done.
