The ruined lighthouse at Waugoshance protects boats from a shoal area at the northern end of Lake Michigan. The lighthouse is located in Emmet County, Michigan, United States, and in U.S. Coast Guard District No. 9. It is approximately 15 miles (24 km) west of Mackinaw City. Due to erosion and deterioration, the lighthouse is deteriorating and critically endangered, and likely to fall into the lake in the near future.

Waugoshance Point is a 2.5-mile-long (4.0 km) cape or peninsula that juts into Lake Michigan from the northwest coast of the Lower Peninsula of the U.S. state of Michigan in Emmet County. It separates the Straits of Mackinac to its north from Sturgeon Bay to the south and is part of Wilderness State Park. The nearest town is Mackinaw City. Waugoshance is a hybrid word, that combines the Anishinaabemowin word wah'goosh and the French word anse.
