This is a list of some of the ways regions are defined in the United States. Many regions are defined in law or regulations by the federal government; others by shared culture and history, and others by economic factors.

===Federal Reserve Banks=== [[File:Federal Reserve Districts Map.svg|thumb|Federal Reserve System districts]] The Federal Reserve Act of 1913 divided the country into twelve districts with a central Federal Reserve Bank in each district. These twelve Federal Reserve Banks together form a major part of the Federal Reserve System, the central banking system of the United States. Missouri is the only U.S. state to have two Federal Reserve locations within its borders, but several other states are also divided between more than one district.
