{{Citation needed}} is a template used to identify claims in articles, particularly if questionable, that need a citation to a reliable source. This template produces the superscripted message [citation needed] and is installed with no spaces directly after punctuation.

Notes[edit source]
- The
|reason=parameter is for an explanation why you think the material needs a source. It is optional but very helpful. It is displayed as a tooltip in some browsers (hover the mouse here[citation needed] to check behaviour of your browser). For example, the following usage might be appropriate to the claim that "Humphrey Bogart was an avid snooker player":
Template:Tnull- Use only plain text for the
|reason=parameter. It does not support wiki markup like wikilinks, which can mess up the tooltip. - Double quotation marks used within the
|reason=parameter will likewise mess up the tooltip; use single quotes or the HTML code"instead. - If omitted, the tooltip "This claim needs references to reliable sources." is used by default.
- Use only plain text for the
- This template should usually be installed directly after punctuation, such as a full stop (period) or a comma.
- Use of this template places the article into Category:All articles with unsourced statements/
- Remove the template when you add a citation for a statement.
Examples[edit source]
Example 1[edit source]
This sentence shows the template used at the end.[citation needed]
This wikitext will be rendered as follows:
- This sentence shows the template used at the end.[citation needed]
Example 2[edit source]
[[Humphrey Bogart]] was an avid snooker player.{{Citation needed|date=Template:Currentmonth Template:Currentyear}}
The template indicates that it may be that Humphrey Bogart played snooker at some point and it may be that he was enthusiastic about the game but no reliable, published sources were given to verify it and the information is not considered common knowledge.
- Humphrey Bogart was an avid snooker player.[citation needed]
Example 3[edit source]
If it is considered that he might have played snooker but was not an avid player, a reason for the need of a citation may be given, displayed as a tooltip when the mouse hovers on "citation needed":
[[Humphrey Bogart]] was an avid snooker player.{{Citation needed|date=October 2024|reason=Only aware he was photographed playing once. Not aware of any source that claims he played a lot.}}
- Humphrey Bogart was an avid snooker player.[citation needed]
In this example, it may be better to use the {{Citation needed span}}, which has slightly different syntax, template to highlight the word "avid".
When not to use this template[edit source]
The {{Citation needed}} template is intended for use when there is a general question of the verifiability of a statement, or when an editor believes that a reference verifying the statement should be provided.
Within an intro that is clearly written as a summary of a substantially sourced article, statements that are supported with citations within the body of the article should not be tagged.
If you have the time and ability to find an authoritative reference, please do so. Then add the citation yourself, or correct the article text. After all, the ultimate goal is not to merely identify problems, but to fix them.
While an editor may add this template to any uncited passage for any reason, many editors object to what they perceive as overuse of this tag, particularly in what is known as "drive-by" tagging, which is applying the tag without attempting to address the issues at all. Consider whether adding this tag in an article is the best approach before using it, and use it judiciously. Wikipedia's verifiability policy requires neither reliable sources for common well-known facts (e.g., "the Moon orbits the Earth"), nor that citations be repeated through every sentence in a paragraph. All direct quotations and facts whose accuracy might be challenged (e.g., statistics) require citations. See WP:MINREF for the list of material that is absolutely required to be followed by an inline citation, rather than a general reference or no citation at all. Also note that the burden of evidence lies with the editor who adds or restores material.
Do not use this template to tag policies or guidelines.
How to respond to this tag[edit source]
The addition of this tag is a request for an inline citation to support the tagged statement. If you are able to provide a citation to support the claim, then please do so.
There is no specific deadline for providing citations. Please do not delete information that you believe is correct solely because no one has provided a citation within an arbitrary time limit. If there is some uncertainty about its accuracy, most editors are willing to wait at least a month to see whether a citation can be provided.
