The Saugeen complex was a First Nations culture located around the southeast shores of Lake Huron and the Bruce Peninsula, around the London area, and possibly as far east as the Grand River.

David Marvyn Stothers, who originally conceptualized the Princess Point complex as an archeological culture, argued in a 1973 article that it and the Saugeen were unrelated.

Therefore, scholars such as Neal Ferris and Michael Spence have proposed abandonment of the framework altogether, or relegation of the terms to purely geographic use, with their replacement by more localized complexes.

Hopewell trading networks were quite extensive, and their valued commodities included obsidian from the Yellowstone area, copper from Lake Superior, and shells from the Gulf Coast.

Within this area, societies participated in a high degree of exchange with the highest amount of activity along waterways, the easiest transportation routes.
