About the Club

With the sound of a gavel striking three times, another Commonwealth Club program begins, bringing together audiences with fascinating, intriguing and entertaining individuals.

The Commonwealth Club of California is the nation's oldest and largest public affairs forum. Every year, we present more than 450 forums on topics ranging across politics, culture, society and the economy. 

The Club has offices in San Francisco and Silicon Valley, with regular events in both areas, as well as programs in Lafayette in the East Bay and in Marin County.

For audiences outside the Bay Area, the Club's weekly radio broadcast—the oldest in the United States, dating back to 1924—is carried across the nation on more than 230 public and commercial radio stations. Our programs are widely podcast and video broadcast. Our website archive features audio and video of our recent programs, as well as selected speeches from our long and distinguished history.
