Oregon is a Mercer county community on the Kentucky River about five miles northeast of Harrodsburg. The site was orginally known as Harrods Landing for James Harrod who settled at Harrodsburg in 1774. A town of Warwick was chartered by the state of Virginia in 1787 and it became an important Kentucky River port. The source of the name is obscure and by 1847 the town was known as Oregon, a name also of unknown origin. A Warwick post office operated in the town from 1889 until 1891 and then on the Woodford county side of the river from 1902 until 1912.

Outside of Oregon is the 1809 Moses Jones house, now maintained by the Warwick Foundation.
