Iowa's 6th congressional district is a formerU.S. congressional district in theState of Iowa. It existed in elections from 1862 to 1992, when it was lost due to Iowa's population growth rate being lower than that of the country as a whole.

The district was created during theCivil War; it was first filled in the1862 general election. Its original representative,Asahel W. Hubbard, was fromSioux City in Northwestern Iowa, but redistricting caused the district to be relocated, first to central Iowa (from 1869 to 1874), then to south-central Iowa (from 1875 to 1932), then the Des Moines area (from 1933 to 1942) and then north-central Iowa (from 1943 to 1962). From 1963 to 1992, the district was made up of counties in the northwestern part of the state.Fred Grandy, the 6th district's last representative, was, like its first, a Sioux City native.
