The World Bridge Federation (WBF) is the international governing body of contract bridge. The WBF is responsible for world championship competitions, most of which are conducted at a few multi-event meets on a four-year cycle. The most prestigious championships are those for national teams in Open, Women, and Seniors categories: the Bermuda Bowl, Venice Cup, and Senior Bowl (jointly the biennial "World Teams Championships"), and the quadrennial World Team Olympiads, incorporated in the World Mind Sports Games beginning 2008.

The World Bridge Federation was founded August 1958 by delegates from Europe, North America, and South America (now Zones 1 to 3). It is incorporated under the laws of Switzerland as a 'non-profit' organization. Harold Stirling Vanderbilt was made the first honorary member of the WBF for his work developing the game. The current president is Jan Kamras of Sweden.

WBF membership now comprises 123 National Contract Bridge Organizations (NBOs) with about 700,000 affiliated members, most of whom participate in bridge competitions locally and many of whom compete nationally and internationally. The NBOs belong to the "zonal organization" in one of eight geographic zones. Each National Contract Bridge Organization agrees to fulfill certain requirements, such as opening its ranks to all its citizens and residents and upholding a standard of ethics acceptable to the WBF.

The World Bridge Federation has a Congress to which each NBO is entitled to send one delegate. The Congress meets every second year, at Team Olympiads and at World Championships. The WBF is administered by an Executive Council which is assisted by the various Committees and Consultants it appoints.

The World Bridge Federation was formed on 18 August 1958 in Oslo, Norway, by delegates from Europe, the US, and South America. Baron Robert de Nexon, an inspiring figure in bridge from France, was elected as first President.

Charles J. Solomon, from the US (1964–1968) and Count Carl Bonde, from Sweden (1968–1970), succeeded Baron de Nexon as WBF President. With the election of Julius Rosenblum in 1970, the WBF started to assume the figure of a real World Organization. Rosenblum strongly believed that bridge needed a visible central organization with global reach rather than conducting its affairs on a local or continental basis.

Rosenblum retired in 1976, and Jaime Ortiz-Patiño from Switzerland was elected president. Under his guidance, the WBF started its new modern era and, in August 1977, was incorporated under the Laws of the State of New York as a not-for-profit organization. The Federation was re-structured as an International Federation devoted to offering its members the best possible service. The stimulation given by Ortiz-Patiño to building the organizational and administrative structure, to developing the discipline and its image, to introducing new rules and a rigid code of ethics is still effective even today. When he left the WBF in 1986 he was elected President Emeritus by acclamation for his exceptional services to bridge.

Denis Howard, from Australia, succeeded him as president from 1986 to 1990. Howard was narrowly re-elected for a second four-year term at a fractious Board of Directors meeting in 1990, where its European members favoured another candidate, José Damiani from France. The ongoing split in allegiance ultimately led to Howard resigning in January 1991 with an understanding that Ernesto d’Orsi from Brazil, who had distinguished himself as a leading bridge administrator, would succeed him on an interim basis. In turn, in August 1992, d'Orsi left the chair to Robert S. Wolff from the US, one of the top players in the history of bridge, to complete Howard's term of office. In August 1994, José Damiani was elected president.
