Leach Railroad Station, is an unincorporated community located 3 miles south of Catlettsburg in Boyd County, Kentucky. It was first established in approximately 1882 as a freight and passenger loading facility for the Chatteroi railroad (later Chesapeake and Ohio Railway). The former community of Leech Station is now mostly owned by Marathon Oil, which operates one of its seven oil refineries there. Marathon bought the large refinery at Leech Station from Ashland, Inc. in 1999. In 2000, Marathon took over ownership of old U.S. 23 and then purchased the remaining residential property located at Leech Station.
