M-104 is a state trunkline highway in the US state of Michigan in the Western Michigan region of the state. It runs from Ferrysburg to Nunica in Ottawa County, passing through Spring Lake. The highway serves as a connector between Interstate 96 (I-96) and US Highway 31 (US 31), helping connect Grand Haven with the Grand Rapids metro area. A related Connector 104 runs between the M-104 and US 31 in Ferrysburg. During the 1920s and 1930s, a different highway bore the M-104 designation. The current highway was previously a section of US 16 until 1940 when that designation was shifted to a road going from Nunica to Muskegon; the orphaned highway was redesignated M-104 at the same time. Since then, two routing changes have caused short segments to be transferred to local control and removed from the highway.

The western terminus of M-104 is at US 31 in Ferrysburg at the north end of the drawbridge spanning the Grand River north of Grand Haven. The highway runs along Savidge Street and crosses a bridge over the channel that connect the river with Spring Lake. On the opposite shore, the trunkline continues along Savidge Street, running between the river to its south and the lake to its north. M-104 crosses the central business area of the village of Spring Lake. East of downtown, the highway transitions to follow Cleveland Street which continues due east to Nunica. The landscape becomes more rural east of Spring Lake where the highway crosses terrain with a mix of open fields and woods. There are various businesses and homes that line the roadway. The eastern terminus of M-104 is located at the exit 9 interchange along I-96 just west of Nunica.
