Mimulus michiganensis (formerly Mimulus glabratus var. michiganensis) is a rare species of flowering plant in the lopseed family, known by the common name Michigan monkeyflower. It is the only plant endemic to the American state of Michigan, where it occurs only in the Grand Traverse and Mackinac Straits areas. It is restricted to a specific type of habitat, and one that is being degraded and lost to development. It was federally listed as an endangered species of the United States in 1990.
