This is a list of some of the regions in the United States.
Official regions of the United States
Many regions in the United States are defined in law or regulations by the federal government.

PADD system was established in World War II and therefore don't accurately reflect current trends. The EIA has updated the PADD system with a complimentary set of regions to reflect this and will change it to suite current needs. (Note: Region 9 includes countries not part of the USA but is included for the sake of completion since it contains Puerto Rico)
