Meet the people making Wikimedia projects more equitable. Discover Open the Knowledge: Stories.

The nonprofit Wikimedia Foundation provides the essential infrastructure for free knowledge. We host Wikipedia, the free online encyclopedia, created, edited, and verified by volunteers around the world, as well as many other vital community projects. 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.

1

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.

2

We respect your data and privacy

We do not sell your email address or any of your personal information to third parties. More information about our privacy practices are available at the Wikimedia Foundation privacy policy, donor privacy policy, and data retention guidelines.

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.

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.

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.
