All of which is made possible thanks to donations from individuals like you. We welcome anyone who shares our vision to join us in collecting and sharing knowledge that fully represents human diversity.

Wikimedia projects belong to everyone
You made it. It is yours to use. For free. That means you can use it, adapt it, or share what you find on Wikimedia sites. Just do not write your own bio, or copy/paste it into your homework.
We respect your data and privacy
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 you and everyone you know can help.
Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Projects with no past or existing affiliation with Wikipedia or the Wikimedia Foundation, such as Wikileaks and wikiHow, also use the term. Although these sites also use “wiki” in their name, they have nothing to do with Wikimedia.
We conduct our own research and partner with researchers worldwide to address change in society and technology.More about research
From site reliability to machine learning, our open-source technology makes Wikipedia faster, more reliable, and more accessible worldwide.More about technology
Collaborative projects are the core of the Wikimedia movement
Our volunteers build tools, share photos, write articles, and are working to connect all the knowledge that exists.
Free encyclopedia written in over 300 languages by volunteers around the world.

Today, scientists can tell us with certainty that increased carbon dioxide emissions are warming the planet. But who was the first to discover this, and when did that happen? I’ll bet it’s earlier than you think. Meet Eunice Newton Foote: a 19th century American scientist, inventor, and women’s rights activist whose contributions to climate science….

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.
Help us unlock the world’s knowledge.
As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.Donate now
