U.S. Highway 52 (US 52) is a 166-mile-long (267 km) United States Numbered Highway in northeast Iowa. The route begins at the Dale Gardner Veterans Memorial 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 US 61 and US 151 before joining the Southwest Arterial, another expressway diverting traffic around the southern edge of Dubuque.

West of Dubuque, the route concurrently follows the US 20 expressway before joining Iowa Highway 136 (Iowa 136) in Dyersville. At Luxemburg, it continues north towards Guttenberg. It then heads northwest where it overlaps US 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.
