M-90 is a state trunkline highway in The Thumb region of the US state of Michigan. It runs from near North Branch eastward to Lexington situated on Lake Huron. The highway is a lightly traveled roadway that runs through rural farmlands. The trunkline runs mostly east–west with two short north–south segments where it turns to run concurrently with other state highways. Along the routing, there are two river crossings and one railroad crossing.

The current highway that bears the M-90 designation is the second to carry number. The first is now a section of M-69 in the Upper Peninsula. A section of current highway gained the number by 1927. Extensions of the highway further east resulted in the current routing by 1934.
