Kissimmee Prairie Preserve State Park, State park and International Dark Sky Park in central Florida, United States.

Kissimmee Prairie Preserve State Park protects the largest remaining tract of Florida dry prairie, an ecosystem shaped by cycles of flooding and fire. It lies next to the Kissimmee River, a headwater of the Everglades, about 40 km (25 mi) north of Okeechobee off US 441. The open grassland is home to the Florida grasshopper sparrow, Audubon's caracara and the Florida burrowing owl.

The preserve protects the largest remaining tract of Florida dry prairie, an ecosystem shaped by cycles of flooding and fire. It lies next to the Kissimmee River, a headwater of the Everglades, within that watershed. The land was ranchland before it became a state park; the current descriptions date protection to 1997, a figure the attached sources do not state.

Stargazers and astronomy enthusiasts gather at designated observation areas to study the night sky without light pollution. The location draws visitors who value pristine natural darkness for celestial viewing.

The park offers multiple camping areas, hiking trails, and equestrian paths open daily from 8 AM until sunset. Visitors should prepare for variable Florida weather and bring sturdy footwear for unpaved surfaces.

Kissimmee Prairie Preserve was the first place in Florida certified as an International Dark Sky Site by DarkSky International. Its night sky measures Bortle 3, dark enough to see the Milky Way and several Messier objects.
