The United States Federal Maritime Commission (FMC) is an independent agency of the United States government that is responsible for the regulation of oceanborne international transportation of the U.S. It is chaired by Daniel B. Maffei.

In the United States government, independent agencies are agencies that exist outside the federal executive departments and the Executive Office of the President. In a narrower sense, the term refers only to those independent agencies that, while considered part of the executive branch, have regulatory or rulemaking authority and are insulated from presidential control, usually because the president's power to dismiss the agency head or a member is limited.
