M-129 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It runs from Cedarville to Sault Ste. Marie. South of Nine Mile Road in Chippewa County (and in all of Mackinac County), M-129 overlays the Michigan Meridian. The section of M-129 that overlays the meridian is named Meridian Road. The highway between M-48 and the northern terminus is a part of the larger Lake Huron Circle Tour.

Originally a part of M-12 and US Highway 2 (US 2), the current roadway was formerly designated M-5 from 1930 until 1939. Two other highways were also previously designated M-129. The first was in the western UP in the late 1920s; it was replaced by M-64. The second was in the Keweenaw Peninsula and was replaced by M-26.
