M-68 is an east–west state trunkline highway located in the northern part of the Lower Peninsula of the US state of Michigan. The western terminus of the highway begins four miles (6.4 km) east of the Little Traverse Bay of Lake Michigan and ends a few blocks from Lake Huron in Rogers City. M-68 skirts just south of Indian River and Burt Lake.

The first incarnation of M-68 existed in the Upper Peninsula before being absorbed into M-35. The current designation was created in 1936. A segment of highway once used by US Highway 23 (US 23) was incorporated into the trunkline as a discontinuous section in the early 1940s until it was later connected in 1946.
