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.
Protect and sustain Wikipedia
Donations are secure
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.
3
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.
Research
We conduct our own research and partner with researchers worldwide to address change in society and technology.

Technology
From site reliability to machine learning, our open-source technology makes Wikipedia faster, more reliable, and more accessible worldwide.

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.

Celebrating eight years of AfroCROWD diversifying Wikipedia
Wikipedia is known for being the world’s largest encyclopedia that anyone can edit—but that does not mean everyone does. Whether due to social, political, or technological barriers that prevent people from sharing what they know with the world, the site is still missing out on a lot of the world’s wealth of knowledge. In particular,….

Black artists belong on Wikipedia — Black Lunch Table is making it happen
The school lunchroom can conjure up all kinds of memories. For the founders of the non-profit Black Lunch Table (BLT), it brought inspiration. The lunchroom offers a shared space for people to come together and connect. Black Lunch Table aims to replicate this experience. Since its founding in 2005, the oral history archiving project has….

Editor since 2013, Wikimedia communityThroughout 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.
