Marshall County is a county located in the far western portion of the U.S. state of Kentucky. As of the 2020 census, the population was 31,659. Its county seat is Benton.
It is the only Purchase Area county that does not border another state; a narrow strip of land in neighboring Livingston County separates Marshall County from the Ohio River and the Illinois border. Until July 28, 2015, it was a dry county. On that date residents approved alcohol sales for off-premises consumption, making it a "wet" county.
