human knowledge
We are the nonprofit that hosts Wikipedia. We support the people, technology, and policies that enable reliable information to be shared with the world.
By the numbers
Wikipedia is the backbone of the internet’s knowledge. From students to chatbots, everyone learns from it.
Wikipedia receives more than
15 billion
views each month.
The Wikimedia Foundation supports nearly
260,000
volunteers every month.
Every minute
342
new edits are made to Wikipedia.
With over 64 million articles, in 300+ languages, Wikipedia is the home of trusted information online.
Wikipedia is the only website among the top 10 most visited that is hosted by a nonprofit organization.
Built for people, by people
Wikipedia is built by nearly 260,000 volunteers from all kinds of backgrounds. They edit articles, check facts, fix code, and help make the internet’s knowledge better. Meet some of them.
Taufik Rosman
The 2023 Wikimedian of the Year, Taufik has been editing since he was 8 years old. He has expanded the Malay Wiktionary with nearly 11,000 changes. “Each of our contributions matters greatly,” Taufik says.
Siobhan Leachman
Siobhan expands English Wikipedia with knowledge about notable women in biodiversity and natural history. Thanks to her, Wikipedia has information about all of New Zealand’s 1,800 endemic moth species.
Armine Aghayan-Flisch
Writing a Wikipedia article each day for a hundred straight days is a feat. Arminé has done it thirteen times on the Armenian Wikipedia, while also uploading over 20,000 open-licensed images.
Donatien Kangah
The most visible part of Donatien’s French Wikipedia work is in the site’s coverage of African football. But behind the scenes, Danatien also runs an organization that expands Wikipedia’s knowledge of Côte d’Ivoire.
Wilfredo Rodríguez
Prolific photographer Wilfredo has shared over 50,000 images with Wikimedia projects. Many come from his home country of Venezuela to preserve its beauty for the world’s benefit.
Ellie Méndez
Ellie has collaborated with multiple El Salvadorean cultural institutions to expand Wikipedia’s coverage of women’s sports in Spanish and train people in updating the site.
Mónica Paola Bonilla-Parra
As the head of Wikimedia Colombia, Mónica works to encourage people to share knowledge on Wikipedia. “There are no limits to participating and contributing,” she says. “If you don’t do it, who will?”
Alberto Leoncio
Most work on Wikipedia happens behind the scenes and is performed by volunteers like Alberto. The time Alberto spends on technical tasks makes life easier for all other Portuguese Wikipedia editors.
Alaa Najjar
Alaa’s nearly 600,000 edits on Wikimedia projects have expanded the sites’ knowledge of medicine, anatomy, and biology. In thanks, he received the prestigious 2021 Wikimedian of the Year award.
Nkem Osuigwe
Nkem is a connector: she brings volunteer Wikimedia editors and librarians from Africa together. Her work in organizing the first African Librarians Week generated nearly 28,000 improvements on Wikipedia.
Ananya Mondal
A clinical nutritionist by trade, Ananya singlehandedly spearheaded an initiative to upload more images of butterflies onto Wikimedia projects. She’s since inspired people to upload over 15,000 new photos.
Netha Hussain
Netha uses her expertise as a doctor to ensure medical content on Wikipedia is accurate, well-sourced, and easily understood—from COVID-19 content during the pandemic to documenting misinformation around women’s health.
Rosie Stephenson-Goodknight
Rosie co-founded the Women in Red project, which is spearheading an effort to increase Wikipedia’s biographies about women in English. So far, they’ve added over 200,000 articles.
Andrew Lih
Long-time Wikipedian Andrew wrote The Wikipedia Revolution, a foundational book on the history of Wikipedia. Over the last two decades, he’s made over 760,000 improvements across Wikimedia projects.
