The World Economic Forum (WEF) is an international non-governmental and lobbying organisation based in Cologny, Canton of Geneva, Switzerland. It was founded on 24 January 1971 by German engineer Klaus Schwab. The foundation, which is mostly funded by its 1,000 member companies – typically global enterprises with more than US$5 billion in turnover – as well as public subsidies, views its own mission as "improving the state of the world by engaging business, political, academic, and other leaders of society to shape global, regional, and industry agendas".

The WEF is mostly known for its annual meeting at the end of January in Davos, a mountain resort in the eastern Alps region of Switzerland. The meeting brings together some 3,000 paying members and selected participants – among whom are investors, business leaders, political leaders, economists, celebrities and journalists – for up to five days to discuss global issues across 500 sessions.

Aside from Davos, the organization convenes regional conferences in locations across Africa, East Asia, Latin America, and India and holds two additional annual meetings in China and the United Arab Emirates. It furthermore produces a series of reports, engages its members in sector-specific initiatives and provides a platform for leaders from selected stakeholder groups to collaborate on projects and initiatives.

The Forum suggests that a globalised world is best managed by a self-selected coalition of multinational corporations, governments and civil society organizations (CSOs), which it expresses through initiatives like the "Great Reset" and the "Global Redesign".

The World Economic Forum and its annual meeting in Davos have received criticism over the years, including the organization's corporate capture of global and democratic institutions, its institutional whitewashing initiatives, the public cost of security, the organization's tax-exempt status, unclear decision processes and membership criteria, a lack of financial transparency, and the environmental footprint of its annual meetings. As a reaction to criticism within Swiss society, the Swiss federal government decided in February 2021 to reduce its annual contributions to the WEF. Furthermore, the WEF is criticized as "hypocritical" towards Palestinian human rights when it rejected a petition from its own constituents to condemn Israel's aggression against Palestinians, claiming it is an "impartial" organization, and then a few months later voluntarily condemned Russia's aggression against Ukraine. The WEF has also been the target of conspiracy theories.

The cost to be paid by companies for a delegate to the WEF were US$70,000 in the early 2000 years, and in 2022 were US$120,000.
