Minnesota State Highway 156 is a highway in Minnesota, which runs from its interchange with Interstate 494 in South St. Paul and continues north to its northern terminus at its interchange with U.S. Highway 52 (the Lafayette Freeway) near downtown Saint Paul.

The route is 4 miles (6.4 km) in length and passes through the city of South St. Paul.

Highway 156 is also known as Concord Street.

State Highway 156 serves as a north–south route between South St. Paul and the "West Side" neighborhood of Saint Paul.

Highway 156 generally follows the Mississippi River throughout its route.

State Highway 156 was marked in 1994. It was originally part of State Highway 56 from 1934 to 1994.

The route was renumbered 156 in 1994 when State Highway 56 was shortened to end at Hampton in southern Dakota County. Nearby Concord Boulevard in Inver Grove Heights (previously State Highway 56 as well) was designated Dakota County Road 56 in 1994.

The route has been paved since the 1920s before it was a numbered highway.
