Rocky Prairie is a Puget prairie that is about 56 miles (90 km) southwest of Seattle, Washington, and about 10 miles (16 km) south of Washington's capital city of Olympia. It sits very close to the Millersylvania State Park, the community of Maytown, and the city of Tenino.
Old Highway 99 runs through Rocky Prairie. The part of the prairie west of the highway is called West Rocky Prairie. Both the west and east sides of the prairie have various plant and animal species. Many of the plant species are flowering plants. Both sides also have areas of Mima mounds (not to be confused with the Mima mounds at Mima Mounds Natural Area Preserve about 10.5 kilometers or 6.5 miles to the west).
