When used with the "This is a redirect" (Redr) template:

Template {{This is a redirect}} may be used to add from one to seven rcat templates, along with their parameters and categories, to a redirect. For more information see the documentation page below.

When used by itself:

  • From an ambiguous term: This is a redirect from an ambiguous page name to a page or list that disambiguates it. These redirects are pointed to by links that should always be disambiguated. Therefore, this template should never appear on a page that has "(disambiguation)" in its title – in that case use {{R to disambiguation page}} instead.
