The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, internet, Wi-Fi, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security.

The FCC was established pursuant to the Communications Act of 1934 to replace the radio regulation functions of the previous Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries in North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of $388 million. It employs 1,433 federal personnel as of 2022.^[update]

As specified in Section 1 of the Communications Act of 1934 and amended by the Telecommunications Act of 1996 (amendment to 47 U.S.C. §151), the mandate of the FCC is, "to make available so far as possible, to all the people of the United States, without discrimination on the basis of race, color, religion, national origin, or sex, rapid, efficient, nationwide, and world-wide wire and radio communication services with adequate facilities at reasonable charges."

Furthermore, the Act provides that the FCC was created, "for the purpose of the national defense," and, "for the purpose of promoting safety of life and property through the use of wire and radio communications."

The FCC is directed by five commissioners appointed by the president of the United States and confirmed by the United States Senate for five-year terms, except when filling an unexpired term. The U.S. president designates one of the commissioners to serve as chairman. No more than three commissioners may be members of the same political party. None of them may have a financial interest in any FCC-related business.

After their terms expire, commissioners may continue serving until the appointment of their replacements. However, they may not serve beyond the end of the next session of Congress following term expiration. In practice, this means that commissioners may serve up to 1+1⁄2 years beyond the official term expiration listed above if no replacement is appointed. This would end on the date that Congress adjourns its annual session, generally no later than noon on January 3.

The FCC is organized into seven bureaus, each headed by a "chief" that is appointed by the chair of the commission. Bureaus process applications for licenses and other filings, analyze complaints, conduct investigations, develop and implement regulations, and participate in hearings.

The FCC has twelve staff offices. The FCC's offices provide support services to the bureaus.
