Minnesota State Highway 175 is a highway in northwest Minnesota, which runs from North Dakota Highway 5 at the North Dakota state line and continues east to its eastern terminus at its intersection with U.S. Highway 59 near Lake Bronson.

The route is 21 miles (34 km) in length and passes through the city of Hallock.

Highway 175 serves as an east–west route between Lake Bronson, Hallock, the Red River, and Joliette, ND.

The route is also known as Broadway Street in Hallock.

The Middle Branch Two Rivers follows Highway 175 throughout its route.

The route is located in the Red River Valley region.

Highway 175 was authorized in 1963 between U.S. 75 at Hallock and the North Dakota state line. The Highway 175 / Highway 5 bridge crossing the Red River at the state line was not completed until the late 1960s.

The section of Highway 175 between U.S. 75 at Hallock and U.S. 59 in Hazelton Township was authorized in 1972.

Highway 175 was paved by the late 1960s between Hallock and the state line after completion of the Red River bridge crossing. The section of 175 between Hallock and Hazelton Township had been paved prior to it becoming a state highway.

State Highway 175 was numbered for its association with U.S. Highway 75.
