M-117 is a 14.479-mile (23.302 km) state trunkline highway in the eastern Upper Peninsula (UP) of the US state of Michigan. The highway connects US Highway 2 (US 2) with M-28 west of Newberry. The designation has been used twice in the UP, once in 1941 for a former section of US 2 between Rexton and Epoufette, and the second in 1949 for the current corridor. The second version included a section that ran north of Newberry along what is now M-123, but it was truncated to its current routing in the 1960s. Since 1993, the trunkline has been dedicated to the 117th Quartermaster Battalion, a former National Guard unit from Kingsford.
