Mima Mounds Natural Area Preserve is a state-protected Natural Area in southwest Washington state, United States. The preserve includes some of the Washington mima mounds, the origin of which still is not fully understood.[2] The site comprises 637 acres (258 ha) of Garry oak woodland, oak savanna, and prairie grasslands.[3][4] Several state and federal endangered species of butterfly depending on the unique prairie conditions can be found in the preserve, including Mardon skipper, zerene fritillary, Puget blue and Taylor's checkerspot.[5]

In 1966, the mima mounds were designated a National Natural Landmark.[6]
