M-98 is the designation of a former 16.2-mile (26.1 km) state trunkline highway in the Upper Peninsula of the US state of Michigan. It ran between M-77 at Germfask and M-28 near McMillan. The highway connected both small towns situated around Manistique Lake when it was designated with the rest of the original state highways in 1919. The section north of Helmer on the east side of the lake ran concurrently with M-135 after the latter's creation in the late 1920s. M-98 was extended at the end of the 1940s before the whole trunkline was removed from the highway system in the 1960s.
