Imagine a world in which every single human being can freely share in the sum of all knowledge.

About us

About the Wikimedia Foundation The Wikimedia Foundation is the nonprofit organization that operates Wikipedia and the other Wikimedia free knowledge projects. Our vision is a world in which every single human can freely share in the sum of all knowledge. We believe that everyone has the potential to contribute something to our shared knowledge, and that everyone should be able to access that knowledge freely. We host Wikipedia and the Wikimedia projects, build software experiences for reading, contributing, and sharing Wikimedia content, support the volunteer communities and partners who make Wikimedia possible, and advocate for policies that enable Wikimedia and free knowledge to thrive. The Wikimedia Foundation is a charitable, not-for-profit organization that relies on donations. We receive donations from millions of individuals around the world, with an average donation of about $15. We also receive donations through institutional grants and gifts.

    Today at 4:45 PM Eastern Time, watch the live broadcast of our WSIS+20 side event, "Building the commons: creating and maintaining digital public goods": https://lnkd.in/e74p36xN 🌐 🌍 🌏 🌎

    New York is bustling this week, with snow and with global digital governance. As the WSIS+20 High-Level Meeting opens at the United Nations, we are gathering to discuss the future of our digital commons and of Digital Public Goods like Wikipedia. At a time when the internet is becoming increasingly fragmented, it is more important than ever to reflect on how our shared digital spaces shape not only our online experience but also our understanding of the world. This is especially true for information integrity, where open knowledge projects built for reliability form the backbone of the global information ecosystem. And it is equally true for the broader digital commons, the public infrastructures that make digital sustainability possible. What do we lose when common online spaces disappear? And how do we make sure that the ones we have are protected and can thrive? How do we ensure that community-led projects working in the public interest continue to exist? We’ll be discussing these and more at the UN this week at our event Building the Commons: Creating and Maintaining Digital Public Goods. 📅 Join us on Tuesday, December 16, from 4:45 to 6:00 PM ET in Conference Room 4 at UN Headquarters (or online) for a panel discussion hosted by Estonia 🇪🇪, France 🇫🇷, the UN Office for Digital and Emerging Technologies, and the Wikimedia Foundation. I'm looking forward to moderating an incredible panel of experts with Priit Turk, Ambassador Philip Thigo, MBS, Lea Kaspar, and Jan Gerlach, and to discussing how to advance a digital future grounded in multistakeholder participation, open knowledge, and community.

  • You may know Wikipedia as a massive, free encyclopedia of articles, but where does the wider Wikimedia movement organize itself? The answer is Meta‑Wiki, a website dedicated to coordination, documentation, and planning across Wikipedia and its sister projects. It hosts policies, guidelines, grant applications, proposals for new initiatives, event pages, and global announcements. Volunteers use Meta‑Wiki to discuss cross‑project issues, vote on changes, share learning patterns, and collaborate on international events like Wikimania. The site supports translation so that important discussions can reach as many communities as possible. Understanding Meta‑Wiki opens the door to participating in governance, helping shape the future of open knowledge beyond writing articles. To start, log in with your existing Wikimedia account, explore pages such as "Community portal" or "Request for comment", and read the guidelines before contributing. You can propose an idea, request funding, or join existing tasks such as translating documentation. Visit the hub of the Wikimedia movement ➡️ https://w.wiki/37o

  • A small edit led to a mission to map a nation. N'da N'dri Konan, also known as User:Dadrik, first logged in to Wikipedia to correct a few lines about his university in Côte d’Ivoire. He quickly noticed that many articles about his country were empty or outdated. Within a year, he had made more than 19,000 edits, created dozens of new articles, and become a patroller on French Wikipedia. As a member of the Wikimedia Côte d’Ivoire community, he organizes edit‑a‑thons, trains newcomers, and advocates for reliable sourcing. He hopes to build a comprehensive repository covering Ivorian history, culture, science, and geography so that future readers can find accurate information about their home. Outside of the Wikimedia movement, Dadrik has a passion for astrophysics, illustrating that curiosity can take many forms. His advice to aspiring Wikipedia editors: start with what you know, ask for help, and remember that every contribution – no matter how small – helps expand free knowledge for everyone. Dadrik's curiosity and commitment to knowledge reflect the very spirit of the Wikimedia movement. For this, he was recognized as the 2025 Newcomer of The Year.

    • Portrait of a man in a light shirt against a blue background with a yellow and green molecule-like pattern. Text says: How a newcomer can quickly become a leader in free knowledge. User:Dadrik turned a single edit into a quest to document his home country of Côte d’Ivoire – and was awarded the 2025 Newcomer of the Year as a result.
    • "What inspires me most is knowing that what I create today will be useful to others, even after I’m gone." Quote by User:Dadrik, 2025 Newcomer of the Year.
  • Here's the truth about how Wikipedia spends donor money ⬇️ As the only one of the world’s 10 most-visited websites hosted by a nonprofit, Wikipedia uses reader support to ensure that billions of people can continue accessing free knowledge. In 2024, a new data center in Brazil improved access for readers and strengthened our global network’s resilience. This is just one example of how your donations make Wikipedia better. 45% of the Wikimedia Foundation's annual budget is spent on technology. This includes server hosting, security, and engineering work that keeps Wikipedia fast, stable, and available everywhere. It also funds improvements that make editing easier across languages – such as the content translation tool, which has helped volunteers create more than 2.4 million articles in over 300 languages. Another 32% of the annual budget goes toward supporting volunteers – the people who write, edit, review, fact-check, translate, and monitor every article. This includes building editing tools, providing anti-vandalism systems, offering grants that help local communities grow, and more. In one recent year, the Foundation awarded more than USD 18 million in grants to 417 groups advancing free knowledge, including support for projects that improve medical and educational content. About 12% of spending covers general operations, including legal work, human resources, finance, and global administration. Another 11% supports fundraising and donor services, including multilingual support for readers in more than 25 languages. The Wikimedia Foundation is consistently recognized as a top-rated, transparent charity. And the details about its support for Wikipedia are all public.

  • The right to seek, receive, and share information is enshrined in international law. Article 27 of the Universal Declaration of Human Rights states that everyone has the right to participate in cultural life and to share in scientific advancement and its benefits, while also respecting the moral and material interests of creators. Access to knowledge underpins justice, freedom, and economic development. Around the world, volunteers on Wikipedia and other Wikimedia projects work to make information available in multiple languages and formats, removing paywalls and barriers that keep people from learning. On International Human Rights Day, we reflect on the role open knowledge plays in advancing equity and dignity. From documenting Indigenous traditions to translating medical articles into underserved languages, contributors help realize the promise that knowledge should be a common heritage. Supporting open licenses, local language projects, and digital access initiatives is part of honoring that right.

  • Licensing high-quality images for sports content can be costly. In an effort to make them more accessible, the Wikimedia Ghana User Group has uploaded over 3,900 high-quality photos from the 13th African Games to Wikimedia Commons. The collection, captured by volunteer photographers Justice Okai-Allottey (User:Owula kpakpo) and Gabriel Joe Amuzu (User:Amuzujoe), is also available as open stock photography for anyone to use freely. Featuring vivid moments from the games, their goal was to help bridge the content gap between the Olympics and other competitions compared to the African Games. To help journalists make the most of these resources, Wikimedia Ghana User Group also hosted a workshop with Ghana's Multimedia Group on how to browse and search for images on Wikimedia Commons and how to provide proper attribution under open licensing.

  • As 2025 comes to a close, Wikimedia Brasil is looking back on their past achievements and preparing for the challenges to come. The organization's new strategy followed a development path that involved broad participation from the Brazilian community. Together, they defined three axes that will guide their actions and intentions for Wikimedia Brasil: Support collaborative practices in favor of free knowledge; Articulate strategic alliances in defense of digital public goods; Promote the wiki methodology for all Portuguese-speaking internet, going beyond the Wikimedia movement.

  • On Wikipedia, differing viewpoints aren't an obstacle. They're a strength. Wikipedia embraces open debate. Volunteer editors care about getting the facts right following the platform's policies, whether they're arguing over pop culture trivia (like Kate Middleton's wedding dress) or deeply serious topics (like documenting COVID-19). No single editor has absolute power: debates happen publicly on talk pages, where everyone can weigh in, and decisions are guided by reliable sources rather than personal opinions. When discussions stall, editors launch a "Request for Comment", or RfC, inviting the broader Wikipedia community to contribute and push the article toward consensus. These practices ensure editor independence, invite diverse views, and prevent undue influence from any one person or organization. Even the Wikimedia Foundation, the nonprofit that hosts Wikipedia, has no say in content disputes on Wikipedia. By channeling conflict into collaboration, Wikipedia shows what the internet can look like when people argue with purpose instead of outrage. Read more ➡️ https://lnkd.in/dECiWSni
