The Commonwealth Club was founded in 1903 and has offices in San Francisco and San Jose, California. Its mission is to be the leading national forum for the impartial discussion of public issues important to its membership, community and the nation. It is the nation’s oldest and largest public affairs forum.
The organization regularly hosts events in both cities, as well as programs in the East Bay and Marin County. For members outside the Bay Area, the club's weekly radio broadcast—the oldest in the U.S., dating back to 1924—is broadcasted on more than 230 public and commercial radio stations across the county. Its website serves as an archive and features audio and video of recent programs, as well as a selection of historical speeches.
The Commonwealth Club offers at least 400 annual events on topics ranging across politics, culture, society and the economy to more than 20,000 members. The club has played host to a diverse and distinctive array of speakers including Theodore Roosevelt, Martin Luther King, Jr., Ronald Reagan, Bill Clinton and Bill Gates.
