The World Wide Web Foundation (also Web Foundation) is an organization dedicated to the improvement and availability of the World Wide Web. It was founded by the inventor of the web, Sir Tim Berners-Lee, who gave the web to the world for free.

The mission of the organization is "to establish the open Web as a global public good and a basic right, ensuring that everyone can access and use it freely". The foundation works in two areas, a free and open Web and Open Democracy, to reach the objectives of the organization.
