Iowa Highway 150 (Iowa 150) is an 85-mile-long (137 km) state highway in eastern and northeastern Iowa. It begins at U.S. Route 218 (US 218) in Vinton and ends at US 52 and Iowa 24 in Calmar. From Vinton, it heads north and east towards Urbana where it meets Interstate 380 (I-380) and Iowa 27, the Avenue of the Saints highway. At Independence, it intersects US 20 on the south side of town. Further north, it converges with Iowa 3 in Oelwein.

As it traverses through the east-central part of the state, Iowa 150 mostly passes through farmland where acreages and farmsteads dot the landscape. Through the towns along the route, the highway generally brings traffic through the central business districts of each town. In Fayette however, the highway bypasses the downtown area. Between Fayette and West Union, part of the route forms the western leg of the River Bluffs Scenic Byway, which passes through Iowa's "Little Switzerland" region.

The Iowa 150 designation has been a part of the primary highway system since its inception in 1920. The current route was formed in 1941. The route extended from Calmar to Davenport, by way of Cedar Rapids. In 1969, the route was truncated at Cedar Rapids, with part of the old route becoming Iowa 130. In 1984, it took its current form when the southern part of the route was shifted over the former Iowa 101. Most of the abandoned part of Iowa 150 became Iowa 920 until July 1, 2003.
