M-48 is an east–west state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It connects Rudyard with Pickford and continues to the far eastern end of the UP. The highway runs for 43.723 miles (70.365 km) through rural parts of Chippewa County, including along the county line with Mackinac County. Between 580 and 1,800 vehicles a day use the roadway daily.

The highway was designated by 1919 along a route that ran much farther west in the UP. Within its first decade, M-48 was extended to end at a point north of Newberry. Since the 1960s, it has had its current configuration. A section of roadway that was previously used as part of the western end of the highway was redesignated as a section H-40 in the 1970s.
