U.S. Highway 151 (US 151) is a US Highway that runs through the states of Iowa and Wisconsin. The southern terminus for US 151 is at a junction with Interstate 80 in Iowa County, Iowa, and its northern terminus is at Manitowoc, Wisconsin. The route, from south to north follows a northeasterly path through Iowa and Wisconsin.

Approximately seven miles (11 km) south of Dubuque, Iowa, US 151 joins with US 61. The two highways share a route from there to Dickeyville, Wisconsin. Three miles (4.8 km) south of Dubuque, US 61 / US 151 join with US 52, and share a route with US 52 until the White Street exit in Dubuque.

In Wisconsin, US 61/151 joins with WIS 35 about one mile (1.6 km) north of the Iowa–Wisconsin border. At Dickeyville, US 151 splits off and heads northeast to Platteville. US 61 and WIS 35 continue north. US 151 later joins with US 18 near Dodgeville. The two highways share a route all the way to Madison.

U.S. Highway 151 starts at an intersection with Interstate 80 (I-80), in an isolated part of Iowa near both Williamsburg and Conroy. It then continues through the area around the Amana Colonies, where it has a brief overlap with US 6. Once meeting up with US 30 and US 218, the route cuts around the city of Cedar Rapids, while the business route 151 goes through the city. The route splits from the other roads and continues toward Dubuque as an expressway. This 65-mile (105 km) stretch crosses many major rivers including both the Wapsipinicon and the Maquoketa. The road eventually goes into the Driftless Area where it meets up with US 61 around the Dubuque Regional Airport. The combined road then heads into the state of Wisconsin where it continues with the US 151 name.
