Simpson Park, officially Simpson Park Hammock, is a 7.8-acre (3.2 ha) urban park and nature preserve located between Brickell and The Roads neighborhoods of Miami, Florida. The park was originally known as Jungle Park, as 5.5 acres (2.2 ha) were set aside in 1913 by a group of individuals to preserve what is now one of the last remaining tracts (along with Alice Wainwright Park and a spot on Virginia Key) of Brickell Hammock, a tropical hardwood hammock which once ran from the Miami River to Coconut Grove.
