About

We share a commitment to free knowledge and work together with our community.

The Wikimedia Foundation is the nonprofit that hosts Wikipedia and our other free knowledge projects. We want to make it easier for everyone to share what they know. To do this, we keep Wikipedia and Wikimedia sites fast, reliable, and available to all. We protect the values and policies that allow free knowledge to thrive. We build new features and tools to make it easy to read, edit, and share from the Wikimedia sites. Above all, we support the communities of volunteers around the world who edit, improve, and add knowledge across Wikimedia projects.

Our Work

We help everyone share in the sum of all knowledge.

We are the people who keep knowledge free. There is an amazing community of people around the world that makes great projects like Wikipedia. We help them do that work. We take care of the technical infrastructure, the legal challenges, and the growing pains.

Host free knowledge projects

The Wikimedia Foundation was established as a nonprofit in 2003 to give Wikipedia a permanent home. We now host 13 collaborative knowledge projects from Wikipedia, the free encyclopedia, to Wikidata, a set of structured data, and beyond. We maintain the servers, build the software, and design the technology that keep these projects running.

Deliver grants for good

We partner with Wikimedia communities around the world to provide them with the support they need to do great work. Last year we awarded over 9 million USD in grants to Wikimedia community members, affiliates and nonprofit organizations. We fund editathons, outreach efforts, events, and conferences. We help them get the word out for free knowledge.

Grow community around the world

When more people can access and contribute to free knowledge, the better that knowledge reflects the world. We are committed to helping grow and sustain a healthy community of over 220,000 people across 170 nations. From the community health initiative to ORES and our work in gender diversity, the Foundation is actively working to make our projects more inclusive.

Support education and learning worldwide

We help teachers and students of all ages access and use the full potential of Wikimedia projects for their learning objectives. Key pillars of our education work include promoting knowledge equity and teaching 21st century skills.

Partner for change

Working with partners like Google, the Metropolitan Museum of Art, and UNESCO, Wikimedia actively seeks new knowledge, closing systemic gaps in global understanding of language, culture, and identity.

Open the Knowledge

“Open the Knowledge” is our call to everyone to promote radical knowledge equity, creating a living record of history, stories, and contexts for and by all people. It aims to make the Wikimedia movement more diverse, equitable, and inclusive.
