U.S. Highway 52 marker

U.S. Highway 52 (US 52) is a 166-mile-long (267 km) United States highway in northeast Iowa. The route begins at the Savanna–Sabula Bridge over the Mississippi River between Sabula and Savanna, Illinois. From Sabula, it heads north along the Mississippi towards Bellevue and Dubuque. At Dubuque, US 52 briefly shares an expressway with U.S. Route 61 and U.S. Route 151.

North of Dubuque, the route follows the course of the river and turns to the west. At Luxemburg, it turns to the north towards Guttenberg. It then heads northwest where it overlaps U.S. Route 18 for 15 miles (24 km). At Calmar, US 52 turns to the north towards Decorah. US 52 crosses into Minnesota north of Burr Oak.

Despite its even number, US 52 is signed as a north–south route. According to the layout of the U.S. Highway System, even-numbered routes are generally signed as east–west routes.
