Chickasaw Park is a municipal park in Louisville, Kentucky's west end. It is fronted to the west by the Ohio River and by Southwestern Parkway to the east. It was formerly the country estate of political boss John Henry Whallen, and began development as a park in 1923, but was not completed until the 1930s. The original plan for Chickasaw Park was designed by the Frederick Law Olmsted firm and is part of the Olmsted Park System, but was a later addition, as Shawnee, Iroquois, and Cherokee Parks were designed in the 1880s by Frederick Law Olmsted himself.
