Marshall County is a county located in far western portion of the U.S. state of Kentucky. As of the 2020 census, the population was 31,659.^[1] Its county seat is Benton.^[2]

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.
