Wikipedia is the nineteenth most accessed website inBrazil[3] and the tenth most accessed inPortugal.[4] As of November 2025[update], it isthe 18th largest Wikipedia by article count, containing 1,160,636 articles. The Portuguese edition is one of the Wikipedias that does not allow edits from unregistered users. It disabled edits from IP editors in 2020.
The Portuguese Wikipedia was the third edition of Wikipedia to be created, simultaneously with other languages. It started its activities on 11 May 2001,[5] having reached the mark of one hundred thousand articles on 26 January 2006.[6]

From late 2004, the edition grew rapidly. In May 2005, it overtook both theSpanish andItalian language Wikipedias. By comparison, in May 2004 it was only the 17th Wikipedia by the number of articles.
Portuguese articles can contain variations of writing, asEuropean Portuguese andBrazilian Portuguese have differences in vocabulary and usage. Articles can contain written characteristics of one or the other variant depending on who wrote the article.
The PortugueseWikipedia community decided not to split a separate Brazilian Portuguese version off from the Portuguese Wikipedia.[7] In 2005, a proposal tofork Portuguese Wikipedia and create a Brazilian Portuguese (pt-br) version was voted down by theWikimedia community.[8][better source needed] In 2007 another one to create a European Portuguese version was rejected too by the Wikimedia community.[9][better source needed] In 2009 another one to create in Brazilian Portuguese was rejected, but this time by the language committee, according to new policies to create new Wikipedia editions,[10][better source needed] with the following explanation:"Brazilian Portuguese is not a separate language.. this is a requirement."[11][better source needed]
Beginning in January 2007,[12] the project experienced a decrease of the share of edits by unregistered users (from around 20 to around 15%) and an increase of the share of such edits being reverted, from about 15% to a peak of 25% in late 2008,[13] which suggests an increase in disruptive editing. In the same month, aJavaScript was added that forced all unregistered users to preview their edit before saving it.[14][better source needed]
In December 2010, the Portuguese Wikipedia overtook theDutch language Wikipedia in number of articles, but in the first quarter of 2011, it was surpassed by theRussian and Dutch language Wikipedias, ranking in the tenth position. In April 2016, the project had 1388 active editors who made at least five edits in that month.

The Portuguese language Wikipedia is different from the English one in a number of aspects.
Until 2009, fair use was not allowed on Portuguese Wikipedia. Debates have been raised before[15][better source needed][16][better source needed] concerning the fair use policy, all of them failing to have the uploading of such images allowed. Uploading pictures at the Portuguese Wikipedia was even fully disabled until then.[17][better source needed] In August 2009, though, a new debate was raised in order for users to approve or deny the creation of a policy of uploading fair use media (named "Uso Restrito de Conteúdo" there, which translates asRestricted Use of Contents). This debate resulted in 142 votes for "yes" against 120 votes for "no", which means the policy was approved and implemented.[18][better source needed][19][better source needed] Nowadays, fair use files are labeled as "Conteúdo restrito", meaning restricted content.
Like English, Portuguese has regional differences in vocabulary, grammar, and spelling. It is widely accepted that an article written in Brazilian Portuguese should be kept as it is, and the same applies to articles in European Portuguese. However, if one rewrites the article in another variant (provided content was changed, not merely the language), but leaves some words in the former variant, these words should be rewritten in accordance with the new version's variant of the article.[20][better source needed]
In order to hinderspamming and trolling, completion of aCAPTCHA image was required for all unregistered users to make any edit. It was disabled on 1 January 2014.[21]
Since 2020, after acommunity vote that lasted from 4 September to 4 October, the Portuguese Wikipedia no longer allows edits from unregistered users (IP addresses).
As of 2019, the Portuguese Wikipedia had 316,000 unique categories, 3.57% of them lacking an appropriate page in the categorynamespace. The average article in this language version has nine categories, while the ratio of unique categories per article is 0.314. The largest number of articles belong to Arts (16%) and Geography (14%) categories. Articles related to Crime and Events have the highest average quality. Those related to Health are read more often, and articles in the Business category have the highest average author interest.[citation needed]
In April 2022, the European Union'sEast StratCom Task Force published its findings that four pro-Russian disinformation outlets (SouthFront,NewsFront, InfoRos andStrategic Culture Foundation) were referenced in 45 articles of the Portuguese Wikipedia. This made it the Wikipedia edition that was the fourth most-affected by such disinformation, after theRussian,Arabic andSpanish Wikipedias.[22] The Task Force wrote:
On the English version of Wikipedia, there seems to be a consensus that state-sponsored disinformation sites aren't legitimate sources[...]. One can only guess whether other language versions will follow suit, but there is nothing stopping anyone from launching that debate, pointing out the English Wikipedia example as a best practice.
