The Wisconsin State Natural Areas Program is a conservation program created to highlight and protect areas with outstanding natural or archaeological resources in the U.S. state of Wisconsin. There are 687 State Natural Areas (SNAs) encompassing almost 400,000 acres (160,000 ha).^[1] SNAs protect natural communities, geological formations, and archaeological sites for research purposes and as refuges for biodiversity and endangered and threatened species.^[1]

Wisconsin's State Natural Areas Program was created in 1951 and was the first state-sponsored program of its kind in the United States. It was developed with guidance from early conservationists such as Aldo Leopold, Norman C. Fassett, Albert Fuller, and John Thomas Curtis.^[2]

The program is managed by the Bureau of Natural Heritage Conservation in the Wisconsin Department of Natural Resources and advised by the Natural Areas Preservation Council (NAPC), a council of 11 scientists and conservationists. The smallest SNAs are fewer than 1 acre (0.40 ha) and the largest is over 7,700 acres (3,100 ha).^[2] Many SNAs have been established on the state owned lands, including Wisconsin state parks. Others are on land managed by other entities like the U.S. Forest Service, National Park Service, county governments, or conservation organizations like The Nature Conservancy. In those cases, cooperative agreements or conservation easements are used.^[2]

Ecosystem management practices range from a "hands-off" approach to active interventions such as the removal of introduced species and controlled burning. SNAs are generally open to low-impact recreation like hiking and birdwatching, but prohibit intensive activities like camping and mountain biking, and usually lack even basic amenities like restrooms or maintained trails. Numerous SNAs are closed to the public to protect the most sensitive flora, fauna, and ecosystems, including rare and endangered species.^[2]
