Iowa's 3rd congressional district is a congressional district in the U.S. state of Iowa that covers its southwestern quadrant, which roughly consists of an area stretching from Des Moines to the borders with Missouri.

From 2013 to 2023, the district covered the southwestern corner of the state, from the Des Moines metropolitan area on the northeastern end to the greater Council Bluffs area on the southwestern end.

The district has been represented in the United States House of Representatives by Republican Zach Nunn since 2023. With a Cook Partisan Voting Index rating of R+3, it is the equal least Republican leaning district (along with the 1st) of Iowa’s four congressional districts, a state currently represented in Congress only by Republicans.[2] It is also the wealthiest congressional district in the state of Iowa.[3]
