Forest Park is a public park located in the western part of the city of St. Louis, Missouri, in the United States. It is a prominent civic center and covers 1,371 acres (5.55 km2). The park, which opened in 1876, more than a decade after its proposal, has hosted several significant events, including the Louisiana Purchase Exposition of 1904 and the 1904 Summer Olympics. Bounded by Skinker Boulevard, Lindell Boulevard, Kingshighway Boulevard, and Oakland Avenue, the park is known as the "heart of St. Louis" and features a variety of attractions, including the St. Louis Zoo, the Saint Louis Art Museum, the Missouri History Museum, and the St. Louis Science Center.

Since the early 2000s, it has carried out a $100 million restoration of its facilities through a public-private partnership aided by its Master Plan. Changes have extended to improving landscaping and habitat as well. The park's acreage includes meadows and trees, and a variety of ponds, manmade lakes, and freshwater streams. For several years, the park has been restoring prairie and wetlands areas of the park. It has reduced flooding and attracted a much greater variety of birds and wildlife, which have settled in the new natural habitats.
