M-79 is an east–west state trunkline highway in the central portion of Lower Peninsula of the U.S. state of Michigan. The western terminus is about three miles (4.8 km) southeast of Hastings at the junction with M-37 and the eastern terminus is in downtown Charlotte at the junction with M-50 and Business Loop Interstate 69 (BL I-69). It passes through Quimby and Nashville, where there is a junction with M-66. The entire highway is undivided surface road. It has no direct access with Interstate 69 (I-69), although a sign for the highway is located on southbound I-69 at exit 61.

The highway was first designated in 1919 between Hastings and Battle Creek. It was later moved to run to Charlotte. A section of M-79 was designated as M-214 in the 1930s. M-214 would later be decommissioned as a highway designation and the M-79 designation was reapplied to the roadway.
