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

Представьте себе мир, в котором каждый человек может свободно делиться всей суммой накопленных человечеством знаний.

Imaginez un monde dans lequel chaque être humain peut librement prendre part au partage de la totalité des connaissances humaines.

تخيل عالمًا يمكن فيه لكل إنسانٍ أن يشارك بحريةٍ في مجموع المعرفة.

Imagina un mundo en el que todo ser humano pueda compartir libremente la suma de todo el conocimiento.

Responding to COVID-19

In this time of uncertainty, our enduring commitment is to provide reliable and neutral information for the world.

The nonprofit Wikimedia Foundation provides the essential infrastructure for free knowledge. We host Wikipedia, the free online encyclopedia, created, edited, and verified by volunteers around the world, as well as many other vital community projects. All of which is made possible thanks to donations from individuals like you. We welcome anyone who shares our vision to join us in collecting and sharing knowledge that fully represents human diversity.

Donations are secure

1

Wikimedia projects belong to everyone

You made it. It is yours to use. For free. That means you can use it, adapt it, or share what you find on Wikimedia sites. Just do not write your own bio, or copy/paste it into your homework.

2

We respect your data and privacy

We do not sell your email address or any of your personal information to third parties. More information about our privacy practices are available at the Wikimedia Foundation privacy policy, donor privacy policy, and data retention guidelines.

People like you keep Wikipedia accurate

Readers verify the facts. Articles are collaboratively created and edited by a community of volunteers using reliable sources, so no single person or company owns a Wikipedia article. The Wikimedia Foundation does not write or edit, but you and everyone you know can help.

Not all wikis are Wikimedia

The word “wiki” refers to a website built using collaborative editing software. Projects with no past or existing affiliation with Wikipedia or the Wikimedia Foundation, such as Wikileaks and wikiHow, also use the term. Although these sites also use “wiki” in their name, they have nothing to do with Wikimedia.

Throughout history, knowledge has been controlled by a powerful few. Wikipedia needs knowledge from all languages and cultures. The internet has become the default for accessing information—women, people of color, and the global south remain underrepresented. We invite you to help correct history.

Help us unlock the world’s knowledge.

As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.
