M-107 was an east–west state trunkline highway in the Upper Peninsula of the US state of Michigan. Running for about 9.6 miles (15.4 km), it connected Lake of the Clouds and the rest of the Porcupine Mountains State Park to M-64 in Silver City. The roadway parallels the Lake Superior shoreline in Ontonagon County.

The roadway was built in 1935 and named to honor the 107th Engineer Combat Battalion. The Michigan Legislature named it the "107th Engineer Memorial Road " in 2001. M-107 was transferred from the control of the Michigan Department of Transportation (MDOT) to the Ontonagon County Road Commission on June 4, 2008. This transfer decommissioned the M-107 designation and removed it from the state trunkline system.

M-107 existed to connect the Porcupine Mountains State Park with the rest of the Michigan state trunkline highway system, running parallel to the Lake Superior shoreline. It began at an intersection with M-64 in Silver City. From there, M-107 ran west into the Porcupine Mountains, crossing the Little Iron River and passing the PMSP Winter Sports Complex. The western end was at the Lake of the Clouds overlook.

Lake of the Clouds is a lake located in Ontonagon County within the Porcupine Mountains Wilderness State Park. The lake is situated in a valley between two ridges in the Porcupine Mountains. Surrounded by wilderness, the lake is a popular destination for hikers, campers, and fishermen. The lake is a prominent feature of the park, and can be viewed at the Lake of the Clouds Overlook at the west terminus of former M-107.
