The Jackson Purchase, also known as the Purchase Region or simply the Purchase, is a region in the U.S. state of Kentucky bounded by the Mississippi River to the west, the Ohio River to the north, and Tennessee River to the east. Although officially part of Kentucky at its statehood in 1792, the land did not come under definitive U.S. control until 1818, when Andrew Jackson purchased it from the Chickasaw Indians. Historically, this region has been considered the most "Southern" of Kentucky.
