Iroquois Park is a 739 acre (3.0 km²) municipal park in Louisville, Kentucky, United States. It was designed by Frederick Law Olmsted, who also designed Louisville's Cherokee Park and Shawnee Park, at what were then the edges of the city. Located south of downtown, Iroquois Park was promoted as "Louisville's Yellowstone". It is built on a large knob covered with old growth forest, and its most prominent feature are the scenic viewpoints atop the hill.
The summit of Iroquois Park presents an all-at-once vista of the city of Louisville, seen from the south. A bronze plaque at the site demonstrates the plan of the city's park and parkway system as planned and executed by Olmsted's firm. The park features an amphitheater, basketball courts, a disc golf course and a riding stable. Broadway at Iroquois (formerly Music Theatre Louisville) stages shows each summer at the park's amphitheater.
Iroquois Park was one of the three major suburban parks created in the late 19th century in Louisville. In 1889, Mayor Charles Donald Jacob purchased Burnt Knob, a 313 acre (1.3 km²) tract of land 4 miles (6 km) south of the city, for $9,000, and was reimbursed by the city treasurer without approval from the city council or public referendum, meaning the original purchase was probably illegal. Jacob also negotiated with landowners between the city and the then-rural park to acquire the right of way for a 150 foot (46 m) wide "Grand Boulevard", today's Southern Parkway, which still leads to the park.
