U.S. Highway 55 was a north–south United States highway. Though it was part of the original 1926 numbering plan, it was deleted within 10 years.

From its southern terminus in Davenport, Iowa, U.S. Highway 55 initially followed the route of present-day U.S. Highway 52 through Hampton, Minnesota excepting for later local improvements such as the Rochester and Decorah bypasses. It was deleted 80 years ago.

North of Hampton, Minnesota, U.S. Highway 55 headed north and west to downtown Minneapolis. Within the village of Hampton, Minnesota, U.S. Highway 55 followed along Main Street and present-day Minnesota Highway 50 to Farmington. Within Farmington, the highway had a shared segment with what was then U.S. Highway 65 (now Minnesota Highway 3) to Elm Street in Hampton.

From Farmington, U.S. Highway 55 headed westward to Burnsville via present-day 212th Street West, Lakeville Blvd, 210th Street West, Kenwood Trail, and Burnsville Parkway to Lyndale Ave (now Interstate 35W). Following the decommissioning of U.S. Highway 55, the portion of the route between Farmington and Burnsville was subsequently designated as a portion of Minnesota Highway 50, and transferred to County control in 1994 as Dakota County Road 50. From Burnsville, U.S. Highway 55 again turned northwards, following Lyndale Avenue across the Minnesota River and into Downtown Minneapolis via Lyndale Avenue, Lake Street, and 3rd Avenue.
