Minnesota State Highway 13 (MN 13) is a 111.694-mile-long (179.754 km) highway in Minnesota that runs from its intersection with U.S. Highway 65 in Albert Lea to its northern terminus at its intersection with State Highway 149 at the West St. Paul / Saint Paul city boundary line.

State Highway 13 serves as a north–south route between Albert Lea, Waseca, Prior Lake, Savage, Burnsville, Eagan, Mendota Heights, West St. Paul, and the "West Side" neighborhood of Saint Paul.

The southern terminus of the route is at the intersection of Main Street and Broadway Avenue (U.S. 65 / Business Loop 35) in the city of Albert Lea.

The northern terminus of Highway 13 is at the intersection of Annapolis Street and Smith Avenue (Highway 149) at the West St. Paul / Saint Paul city boundary line.

Highway 13 is built as a divided highway between Savage, Burnsville, and Eagan. This portion of the route is a busy metro area corridor paralleling the Minnesota River.

At the junction with CSAH 101 in Savage, leading to US 169, Highway 13 turns east. This junction is a hybrid: traffic moving from CSAH 101 toward Highway 13 is grade separated, with through traffic connecting to Highway 13 north, and with exit and entrance ramps connecting to Highway 13 south; southbound traffic on Highway 13 uses a continuous green T-intersection, while through traffic connects to CSAH 101.

Highway 13 is also built as a divided highway in Mendota Heights between I-494 (no interchange / junction) to State Highway 55. The section of Highway 13 north of State Highway 55 at Mendota is far less busy.

Highway 13 is also known as Sibley Memorial Highway in Lilydale, Mendota, and Eagan.
