Representing your ideas—and interests—in Washington for nearly a century.

The U.S. Chamber of Commerce is the world's largest business federation representing more than 3 million businesses of all sizes, sectors, and regions. It includes hundreds of associations, thousands of local chambers, and more than 100 American Chambers of Commerce in 91 countries.

Whether you own a business, represent one, lead a corporate office, or manage an association, the Chamber of Commerce of the United States of America^®  provides you with a voice of experience and influence in Washington, D.C., and around the globe. Our core mission is to fight for business and free enterprise before Congress, the White House, regulatory agencies, the courts, the court of public opinion, and governments around the world.

From its headquarters near the White House, the Chamber maintains a professional staff of more than 300 of the nation's top policy experts, lobbyists, lawyers, and communicators. The Washington staff is supported by eight regional offices around the country; offices in New York and Brussels; an on-the-ground presence in China; and a network of grassroots business activists.

Our members include businesses of all sizes and sectors—from large Fortune 500 companies to home-based, one-person operations. In fact, 96% of our membership encompasses businesses with fewer than 100 employees.

The leadership is equally diverse, with more than 100 corporate and small business leaders from all sectors serving on the board of directors. 

If your organization is not a member of the U.S. Chamber, there are plenty of reasons it should be. ...Reasons to Join
