The HTTP referer (originally a misspelling of referrer<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>) is an HTTP header field that identifies the address of the webpage (i.e. the URI or IRI) that linked to the resource being requested. By checking the referrer, the new webpage can see where the request originated.

In the most common situation this means that when a user clicks a hyperlink in a web browser, the browser sends a request to the server holding the destination webpage. The request includes the referrer field, which indicates the last page the user was on (the one where they clicked the link).

Referer logging is used to allow websites and web servers to identify where people are visiting them from, for promotional or statistical purposes.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
