|This page in a nutshell: A double redirect is a redirect to another redirect. The MediaWiki software is not programmed to follow these redirects. Double redirects are easily fixed by bots, and human editors should devote their efforts elsewhere. However, an editor should not leave behind the double redirects that they created themselves.|

A redirect is a special type of page that automatically causes another page to be displayed in its place. A redirect that points to another redirect is called a double redirect. These pages are unwanted, because Wikipedia's MediaWiki software is currently configured to not follow the second redirect. The MediaWiki feature which will allow it is not mature yet. If someone is redirected to a redirect, the chain stops after the first redirect, like in the example. These situations create unpleasant experiences for the reader and make the navigational structure of the site confusing.
Double redirects are usually created after a page move, when old redirects are left unchanged and pointing towards an old name. Although bots fix most of these within a few days from creation automatically, editors should take care not to manually create double redirects.
Double redirects are easily and automatically fixed by bots, and most are fixed within a few days of creation. Because of this, human editors would be best off-putting their time on other tasks that can't be automated. However, bots will not fix a double redirect if the redirect page is fully protected. The following bots fix double redirects:

This list was compiled from Wikipedia:Bots/Status.
Suppose you want to check whether there are any double redirects to page C. Go to page C and click "What links here" (usually the first link in the "Toolbox" on the left-hand side of the page). Double (or multiple) redirects are those pages which appear in the list with both of these properties:
Note that if you've just moved page C, then there might be only one page which is not indented, (the page at the top of the list), and everything else might be indented at least one level.
Once all double redirects have been fixed, the "What links here" page will have only three types of pages listed:
The first and third categories do not need to be fixed – see Wikipedia:Redirect#Do not "fix" links to redirects that are not broken.
MediaWiki will not follow a redirect if:
