In the United States, a county is a geographic subdivision of a state , usually assigned some governmental authority. The term "county" is used in 48 of the 50 states; Louisiana is divided into parishes and Alaska into boroughs. Parishes and boroughs are called "county-equivalents" by the U.S...

. No attempt has been made to differentiate between these various divisions as to whether or not they "count" toward the total of county boundaries.

This incomplete list is based on the "adjacent counties" section found in most articles on individual U.S. counties insofar as whether it considers contact with or between single points of territory as representing a boundary of "zero" length.

Previously only about a dozen U.S. counties were noted in their respective articles as bordering eight other counties, along with about a dozen others that bordered nine or more. These counties were typically described as "one of only a few," and several were erroneously described as the only such county in a particular state. However, there are in fact fifteen counties in the state of Georgia alone that border eight or more other counties. Approximately 180 U.S. counties border eight others counties (nearly 6% of the total); nearly fifty border nine others (1.5%), and nearly twenty border ten or more. Only five of the fifty states (Connecticut
