Iowa Highway 15 begins 7 miles (11 km) east of Pocahontas at Iowa Highway 3. It goes north for 5 miles (8.0 km) to Rolfe, then begins to go northeast in a stairstep manner for 9 miles (14 km) until crossing the West Fork of the Des Moines River and into Humboldt County 3 miles (4.8 km) west of Ottosen. It then turns north onto the Palo Alto County/Kossuth County border for 41⁄2 miles (7.2 km) and passes through West Bend. It continues north for 81⁄2 miles (14 km) to the Whittemore area, where there is a one-mile (1.6 km) overlap with U.S. Route 18, where it fully enters Kossuth County.
It goes north 9 miles (14 km) to Fenton, continues north for 6 miles (9.7 km), and then turns west for 3 miles (4.8 km), where it enters Emmet County. Near Ringsted, it turns north again for 61⁄2 miles (10 km) and meets Iowa Highway 9 in Armstrong. Iowa 9 and Iowa 15 overlap each other for two blocks before Iowa 15 turns north into Armstrong. Highway 15 leaves Armstrong to the east; 3 miles (4.8 km) east of town, it turns north and ends at the Minnesota border 7 miles (11 km) later.
Parts of what is now Iowa Highway 15 were originally primary roads designated in 1926. Primary Road 44 extended from Primary Road 10, now Iowa Highway 3 to Rolfe, while Primary Road 43 extended from Armstrong to the Minnesota state line.[3] By 1947, Iowa Highway 44 had been created along the same route Iowa 15 now occupies.[4] In 1969, then-Iowa Highway 44 was redesignated as Iowa Highway 15 to match Minnesota State Highway 15 at the state line.[1]

Prior to July 1, 2003, there was a second Iowa 15 in southern Iowa. That route extended 41⁄2 miles (7.2 km) south from Iowa Highway 2 to the Missouri state line where it became Missouri Route 15. Iowa 15 was replaced by Van Buren County Road V56 and is currently signed as 'To Missouri Route 15' at the intersection with Iowa 2.[6] The southern Iowa Highway 15 was originally designated as Primary Road 11 in 1926. [7] By 1947, this highway had been designated Iowa Highway 23.[4] In 1969, it too was designated as Iowa Highway 15 to match Missouri Route 15 at the state line.[1]
In 2002, the southern Iowa 15 was selected with over 700 miles (1,100 km) as low-traffic roads that should be turned over to county jurisdictions.[8] The transfer to Van Buren County took place when the law went into effect on July 1, 2003.
