The World Bridge Federation (WBF) is the international governing body for contract bridge.
Emulating the organizational concepts of the Olympic movement and its signature five rings, the World Bridge Federation encompasses the five continents (America, Europe, Africa, Asia and Oceania) represented by eight geographic Zonal Conferences. Each Zonal Conference consists of member countries as represented by their respective National Bridge Organization.
