Make a difference. Join a Wikimedia campaign today!


Every year, dozens of volunteer- and partner-led campaigns take place around the world to strengthen Wikipedia and other free knowledge projects.


Whether it is by adding missing references, uploading photographs, or creating new biographies on overlooked women, you can impact the information people around the world use on a daily basis.


At almost any time of the year, a campaign or contest is happening that you can get involved with. Explore the campaigns below, or contact your local affiliate if you are looking for more opportunities.


You could be part of organizing a campaign too. Learn more in our organizer portal.

Take photos, illustrate Wikipedia

Do you like to take photos? Help visually document the world on Wikipedia and beyond! Check out annual photography contests below, or join a monthly photo challenge on Wikimedia Commons.

Make small changes with a big impact

It might only take you a few minutes, but adding a citation or a photo to Wikipedia can have an impact that lasts for decades.

Close cultural content gaps

Wikipedia is missing many kinds of information. Join one of these international efforts to identify topics and write about them internationally.

Improve representation, address biases

Wikipedia is powered by humans, so it is vulnerable to human biases. It is also a reflection of structural and historical inequalities in opportunity and representation experienced by many groups around the world. Join other volunteers who are working to ensure Wikipedia represents the full, rich diversity of all humanity.

Help us unlock the world’s knowledge.

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