Iowa's 9th congressional district existed from 1873 to 1943. The district was configured four times, first as part of a nine-district plan, then twice in eleven-district plans, then again in a nine-district plan. In the nine-district plans, the Ninth District encompassed the northwestern corner of Iowa, but in the eleven-district plans it encompassed Council Bluffs and nine surrounding counties.
