The Mero site is a stratified, multicomponent prehistoric site located on the south side of Marshall's Point on the Door Peninsula in Door County, Wisconsin. It was excavated in 1960 by Ronald and Carol Mason under the auspices of the Neville Public Museum in Green Bay, Wisconsin, with financial backing from the landowner, Peter Mero. As of 2016, Marshall's Point is a gated residential community. The privately owned interior of the community is recognized as a Wisconsin State Natural Area.
