List of Wikipedias
Wikipedia is a free multilingual wiki-based open-source online encyclopedia edited and maintained by a community of volunteer editors, started on 15 January 2001 as an English-language encyclopedia. Non-English editions followed in the same year: the German and Catalan editions were created on 16 March, the French edition was created on 23 March, and the Swedish edition was created on 23 May. As of October 2025, Wikipedia articles have been created in 357 editions, with 343 currently active and 14 closed.
The Meta-Wiki language committee manages policies on creating new Wikimedia projects. To be eligible, a language must have a valid ISO 639 code, be "sufficiently unique", and have a "sufficient number of fluent users".
Wikipedia projects vary in how they divide dialects and variants. For example, the English Wikipedia includes most modern varieties of English including American English and British English. Similarly, the Catalan Wikipedia encompasses all Catalan variants, like Valencian, Balearic or France's Catalan; Spanish Wikipedia includes both Peninsular Spanish and Latin American Spanish; and the Portuguese Wikipedia includes both European Portuguese and Brazilian Portuguese. In contrast, some languages have multiple Wikipedias. For example, Serbo-Croatian encompasses four Wikipedia editions, Serbo-Croatian and three different standardized varieties (Bosnian, Croatian, and Serbian).
Additionally, some Wikipedia projects apply different approaches to orthography. For instance, the Chinese Wikipedia automatically transliterates between six standard forms: three using simplified Chinese characters (Mainland China, Malaysia, and Singapore) and three using traditional Chinese characters (Taiwan, Hong Kong, and Macau). And rather than relying on transliteration, Belarusian has separate Wikipedia projects for the official Narkamaŭka and Taraškievica orthographies.
Each Wikipedia project has a code, which is used as a subdomain of wikipedia.org. The codes mostly conform to ISO 639-1 two-letter codes or ISO 639-3 three-letter codes, with preference given to a two-letter code if available. For example, en stands for English in ISO 639-1, so the English Wikipedia is at en.wikipedia.org.
The table below lists all the language editions of Wikipedia roughly sorted by the number of active users (registered users who have made at least one edit in the last thirty days).
The Nostalgia Wikipedia is an archive of the English Wikipedia's initial display.
