Our mission is to empower a global volunteer community to collect and develop the world's knowledge and to make it available to everyone for free, for any purpose. Projects include: Wikipedia, Wiktionary, Wikiquote, Wikibooks, Wikisource, Wikispecies, Wikinews, Wikiversity, Wikivoyage, Wikimedia Commons, Wikidata, MediaWiki, Meta-Wiki, Wikimedia Incubator, and Wikimedia Labs.
Wikipedia is the world's largest and most popular encyclopedia. It's online, free to use for any purpose, and free of advertising.
Above all, the Wikimedia Foundation exists to support and grow the vast network of volunteers who write and edit Wikipedia and its sister projects - more than 100,000 people around the world.
It has become the largest collection of shared knowledge in human history. The people who support it are united by their love of learning, their intellectual curiosity, and their awareness that we know much more together, than any of us does alone.
Support this important cause by creating a personalized fundraising page.
