M-189 is a north–south state trunkline highway in the Upper Peninsula of the US state of Michigan. It serves as the continuation of Highway 139 (WIS 139) from Wisconsin into Michigan, connecting to US Highway 2 (US 2) in Iron River. M-189 has been largely unchanged since being designated in the 1930s, although a new bridge over the Brule River at the state line was built in 1988.
