Mount Arvon, Mountain summit in Upper Peninsula, Michigan, United States

Mount Arvon rises to 1,979 feet (603 m) in the Huron Mountains of Baraga County, about eight miles south of Lake Superior. A blue diamond-shaped metal sign reading "MOUNT ARVON" and "HIGHEST POINT IN MICHIGAN" stands on a slender gray post in a dirt and leaf-covered clearing among trees, behind a wooden picnic table and beside a wooden post holding a blue mailbox.

Mount Curwood was long accepted as Michigan's highest point until a 1982 resurvey with modern technology found Mount Arvon 1 foot (0.30 m) taller. A 2025 survey reversed this again, determining Mount Arvon lies 0.4 feet (0.12 m) lower than Mount Curwood.

The summit sign is a blue diamond-shaped metal marker reading "MOUNT ARVON" and "HIGHEST POINT IN MICHIGAN", set on a gray post in a dirt clearing with a wooden picnic table and a blue mailbox nearby. The name Arvon comes from a literary source rather than local usage, and the mailbox holds a summit register where visitors leave notes.

Access is by forest roads from L'Anse, with the final approach as a short walk from the parking area. The route is straightforward and the climb to the summit takes only a short time.

The summit is not the highest surface point in Michigan: a 2018 NOAA report put the top of the Tilden Mine waste pile near Ishpeming slightly above 2,000 feet, over 20 feet higher. A 2025 resurvey also placed Mount Arvon 0.4 feet below Mount Curwood, reversing the 1982 result.
