M-38 is an east–west state trunkline highway in the Upper Peninsula (UP) of the U.S. state of Michigan. Its west end starts in Ontonagon and runs east to Baraga, some 42.225 miles (67.955 km) apart. The highway crosses streams and rivers in forest lands and provides access to a casino. The east end is located by the Keweenaw Bay of Lake Superior in the Keweenaw Bay Indian Community.

There have been two highways in the state to carry the designation. The first was located in the southeastern Lower Peninsula. The current version of M-38 was created from a section of M-35 in the 1960s. This section was orphaned from the rest of M-35 when the highway was cancelled through the Huron Mountains.
