Indiana's 3rd congressional district

Indiana's 3rd congressional district is a congressional district in the U.S. state of Indiana. Based in Fort Wayne, the district takes in the northeastern part of the state. This district includes all of Adams, Allen, Blackford, DeKalb, Huntington, LaGrange, Noble, Steuben, Wells and Whitley counties, as well as northern Jay and northeast Kosciusko counties.

The district is currently represented by Republican Marlin Stutzman, who succeeded fellow Republican Jim Banks after the latter retired to run for Senate in 2024. Stutzman previously held in the same district from 2010 to 2017.

The district and its predecessors have typically been strongly Republican. It occasionally elected Democrats in the past, but the Democrats have not come close to winning it since 1994. Pockets of Democratic influence exist in Fort Wayne itself, which frequently elects Democratic mayors and occasionally sends Democrats to the state legislature. However, this is nowhere near enough to overcome the overwhelming Republican lean of the rest of the district.
