Throughout history, knowledge has been controlled by a powerful few. Wikipedia needs knowledge from all languages and cultures. The internet has become the default for accessing information—women, people of color, and the global south remain underrepresented. We invite you to help correct history.Join the movement

KEY INFORMATION — POINTS CLÉS
Things to know
Wikimedia projects belong to everyone
We respect your data
People like you keep Wikipedia accurate
Readers verify the facts. Articles are collaboratively created and edited by a community of volunteers using reliable sources, so no single person or company owns a Wikipedia article. The Wikimedia Foundation does not write or edit, but others can help.
Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Hundreds of organizations and projects with no affiliation with Wikipedia or the Wikimedia Foundation also use the term, including wikiHow and WikiEducator.
Wikimedia has nothing to do with Wikileaks and never did. Although both use the term “wiki” in their name, they have always been completely separate and unaffiliated.
Help us unlock the world’s knowledge.
As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.Donate
