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".[5]
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.[14] For example, en stands for English in ISO 639-1, so the English Wikipedia is at en.wikipedia.org.

The table below lists the active 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).[15]

Retrieved 21 December 2020. Wikipédia, l'encyclopédie collaborative libre, fêtera ses dix ans en janvier 2011, et a débuté le 23 mars 2001 en version française, mais dès ce jeudi 23 septembre, à neuf ans et demi exactement, la Wikipédia francophone a enregistré officiellement le cap du million d'articles. (Wikipedia, the free collaborative encyclopedia, will celebrate its tenth anniversary in January 2011. It started on March 23, 2001 in its French version, but as of this Thursday, September 23, at exactly nine and a half years old, the French-language Wikipedia has officially reached the one million article mark.)

No passado, as tensões motivadas pelas variantes idiomáticas levaram a propostas para a criação de Wikipédias separadas para o português brasileiro e europeu. Tentativas nesse sentido lançadas em 2005, 2007 e 2009 foram rejeitadas pela Wikimedia Foundation, sob pretexto de que não se trata de idiomas suficientemente diferentes para justificar a cisão.
