Wikipedia 25
As of 2024, the new project proposals process is under review by the Wikimedia Foundation Board. You can still submit proposals, however please note that no new projects will be accepted until this review is complete.
- To propose a new language for an existing project, see Requests for new languages.
- To propose closing an existing project, see Proposals for closing projects.
- To suggest an enhancement which requires a change to MediaWiki, file a feature request in Phabricator.
- To propose enhancements to an existing project, visit that project and gather interest there.
Notes to consider
- Hosting: Wikimedia Foundation is not a free hosting company. If your project does not fit the Foundation's ideals, download MediaWiki for free and install it on a server you control. Fandom (formerly Wikia), ourproject.org, or other wiki farms are also options, but you need to evaluate what extent you can take control of your wiki project in that wiki farm.
- Need a dedicated project? Think well. Maybe your proposal fits better into one of the existing projects, for example, Wikipedia, Wikibooks, or Commons?
- History: Individuals attempting to create a new project should read the Wikipedia timeline.
- Be persistent. Don't take criticism personally. Some users are afraid of repeating mistakes from past projects. Going from an idea to a working wiki takes time and editing and sometimes software development. Be prepared for criticism; if it is a good idea, others will help you out!
- Demo: It may be useful to start a demo of the wiki along with the proposal. Demo wikis can be created at Wikispore, which is a proposed wiki for seeding new WMF projects. You can also use Fandom, ourproject.org, or any other wiki farm.
The last project to be created was Wikifunctions in 2023. See the history of the project proposal page for Wikidata before it went live. The last one before that was Wikiversity in 2006. Some proposals below are suggesting adopting existing projects. The only time this has happened was when Wikitravel was forked as Wikivoyage and integrated into the Travel guide proposal in 2013. Creating new projects is extremely rare but not impossible. Please consider if what you are proposing is really a new type of information or educational project that cannot fit within the scope of existing projects.
Existing projects
see also the Complete list of Wikimedia projects
Some common proposals could be merged into one of these as a subproject.
- Wikipedia has many WikiProjects. Your proposal could be one, or part of one.
- Wikisource has WikiProjects for primary sources and historical documents.
- Wikibooks hosts some collections: Wikijunior (children's books), and the Cookbook.
Other content projects may be a good fit for what you have in mind:
- Wikimedia Commons (images & media)
- Wikispecies (taxonomic database)
- Wikiquote (quotations)
- Wiktionary (dictionary and thesaurus)
- Wikiversity (educational materials)
- Wikivoyage (travel guide)
- Wikidata (data repository)
- Incubator wiki (new language editions of most Wikimedia projects; see Beta Wikiversity and Multilingual Wikisource for those projects)
Content project that is closed:
- Wikinews (collaborative journalism)
Instructions
- Create an account and a user page on this wiki, so people can address questions to you.
- Create a page describing your plan: enter the project name in the box below and click the button.
- Link to your proposal from this page, below.
- Advertise your project! Good places to do so are on the Wikimedia Forum and the wikimedia-l mailing-list.
There was a proposed reform of new project process and a proposed community committee to develop a clear policy and documentation for sister project proposals, both of which are currently inactive. The de facto process is described below:
- Any proposal may only be approved by the Board of Trustees after a prominent discussion process and a broad and clear consensus (dozens and probably hundreds of supports are needed, and the proposal may be open for years)
- Any users in good standing may close or merge any proposal if:
- it is clearly redundant to another project or project proposal, or is not a serious or intelligible proposal— i.e. jokes, trolling, proposals with extremely vague scope, and patent nonsense (tag "Procedurally closed");
- it is stale and has few support after a considerable amount of time (tag "Stale");
- it clearly has no consensus after a considerable amount of time (tag "Rejected").
Unless your proposal involves new features that the MediaWiki software currently doesn't have, you may incubate your proposal in Wikispore, an unofficial project to develop test wikis. |
Wikipedia turned 25 on 15 January 2026
This Wikipedia 25 Meta-Wiki page is a framework for the global Wikimedia movement to coordinate around the 25th anniversary of Wikipedia. The celebration will last throughout 2026. We are celebrating 25 years of knowledge, humanity, and collaboration at its best. Together and piece by piece, we build the sum of all human knowledge.
Explore these resources to help you plan, promote, and share in celebrating Wikipedia’s 25th anniversary – before, during, and after the festivities:
- A space to organize and plan events and meetups to celebrate the 25th,
- Tips and inspiration on how to organize and run an event,
- A celebration toolkit of visual assets to share and celebrate,
- A collection of tips for pitching to local media,
- A guide on using social media to spread awareness,
- A place to share birthday photos, videos, stories, and more.
Get involved

- Find an event nearby or remotely or find some helpful resources to help you plan one. We already have more than 70 events, and hope to have many more.
- Talk to the local press. Resources, including a press release template and resources on working with the media, are available to support you in your press outreach efforts.
- Use Wikipedia 25 materials. We’re inviting you to make your own illustrations, apparel, presentations, and branded elements with the templates and guidelines here.
- Help with translating. Help us get the word out about Wikipedia 25 in as many languages as possible by joining our translation efforts!
- Want to add a cute 25th birthday mascot to your Wikipedia? Get in touch with the team to take part in this experiment to create a special feature with fun “easter egg” surprises for readers starring Baby Globe. This special feature will be available from 16 Feb 2026 till 6 April 2026 on the Wikipedia portal page, and any interested Wikipedias.
- Pre-order a Baby Globe plushie, Wikipedia’s curious little birthday mascot.
- Watch and share our 9-part social media docuseries
- Wish Wikipedia a happy birthday! Use the “Add Yours” sticker on Wikipedia's Instagram to share your wishes. We aim to later stitch all wishes together to create the longest birthday card.
Approach
See below for some general things to know about the overall approach for the 25th birthday celebration:
- Based on our experience celebrating Wikipedia's 20th birthday five years ago, we know this celebration is a time when we will have the world's attention. Our goal is to capitalize on this moment to reach a broad, public audience with our key messages and calls to action. The 25th birthday celebration is a feel-good moment of impact.
- While the technical birthdate is 15 Jan. 2026, the celebration will have a much longer lifespan. We will begin building excitement about the birthday in November 2025. The main communications campaign will launch in January 2026 while we celebrate the in-person event as a movement at Wikimania Paris. Movement and partner activities and events will happen throughout the 2026 calendar year.
- The 25th birthday celebration is not about English Wikipedia. It is about the birth of Wikipedia as a concept — a creation that has evolved to be in over 300 languages.
We hope that people around the world, in as many countries as possible, celebrate Wikipedia's 25th birthday. To support this goal, the 25th birthday celebration will include a global campaign centered on the existing “Knowledge is Human" theme.
