In the U.S. state of Minnesota, Interstate 90 traverses the southern side of the state, parallel to the Minnesota-Iowa state line. The route connects the cities of Rochester, Worthington, Albert Lea, and Austin. The city of Winona is also in close proximity to I-90, with about 10 miles away separating the interstate and the city.

Interstate 90 in Minnesota is 276 miles (444 km) in length. The route crosses the far southern parts of the state.

Interstate 90 enters the state from South Dakota near Beaver Creek. This part of Minnesota has flat to gently rolling terrain and is the beginnings of corn belt farmland. The flat terrain is often subject to blowing and drifting snow in colder months, and the western portions of the highway are closed multiple times each winter.

Rock County, where I-90 enters Minnesota, is one of the only counties in the state lacking a natural lake. The change from semi-arid to a wetter climate happens slowly moving eastbound on I-90 through southern Minnesota. The route passes through the cities of Luverne, Adrian, Worthington, Jackson, Fairmont, and Blue Earth. I-90 has a junction with I-35 at Albert Lea.
