About us
We are the nonprofit organization that operates Wikipedia and the other Wikimedia free knowledge projects. We host a technology infrastructure that makes possible billions of monthly visits to Wikipedia. Since 2003, we have supported the hundreds of thousands of volunteer editors who edit, expand, and curate the Wikimedia projects. We equip these volunteers with the most up-to-date tools, ensure connections to Wikipedia are fast, safe, and private, and develop new technology and products to meet the demands of our readers and editors. We provide individuals and organizations around the world with funding to increase the knowledge on Wikipedia. We also undertake legal and advocacy efforts to protect people’s right to free knowledge. We are 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 $11. We also receive donations through institutional grants and gifts. We are a United States 501(c)(3) tax-exempt organization with offices in San Francisco, California.

Wikipedia helps shape how millions of people learn about the world. Now, it’s also helping shape the AI systems and large language models that power how people find information. But Asian American history is still underrepresented, leaving important people, stories, and contributions missing from one of the internet’s most consulted resources. To bridge that gap and move knowledge equity forward, the Committee of 100 launched its free Wikipedian Fellowship. The eight-week online program trains community and nonprofit leaders to write, edit, and expandWikipedia articles about Asian American subjects. The inaugural cohort brings together representatives from more than a dozen Asian American-focused nonprofits, foundations, and advocacy organizations, all working to make this history more visible and accessible.

On 12 August 2026, a total solar eclipse will cross Greenland, Iceland, Spain, and other locations, while much of Europe, northwestern Africa, Canada, and parts of the northern United States will see a partial eclipse. In parts of mainland Europe and Africa, the Sun will set while it is still partially eclipsed, creating an opportunity to document a sunset eclipse. If you're somewhere along the eclipse's path, your photos could help illustrate history on Wikimedia Commons. Be sure to use proper solar filters when viewing or photographing the partial phases of the eclipse. Eclipse glasses do not protect camera lenses. Learn how to upload files ➡️ https://w.wiki/STXk

Why does data matter? Every day, volunteers add machine‑readable data to Wikidata – information like dates, places, and relationships that connects knowledge across the Wikimedia ecosystem. That data helps link articles across languages; powers infoboxes, charts, and interactive maps; and makes it easier to discover connections between people, places, and concepts. Most people never see this infrastructure, but it’s part of what enables Wikipedia and other Wikimedia projects to be a growing interconnected ecosystem of free knowledge. Wikidata also powers countless tools and services beyond Wikimedia, including WikiFlix, Cartes, and Expeditia. Discover more about the world of data ➡️ https://w.wiki/8m49

Starting something new can be intimidating. Fortunately, Wikipedia has a place built specifically for newcomers: the Teahouse. It's a friendly space where new editors can ask questions about editing, sourcing, community norms, or anything else they're curious about contributing to Wikipedia. Experienced volunteers stop by to offer guidance, share advice, and help newcomers find their footing. Remember, every experienced Wikipedian started somewhere! Have a question about editing?
