Montana's second congressional district is a congressional district in theUnited States House of Representatives that was apportioned after the2020 United States census. The first candidates ran in the2022 elections for a seat in the118th United States Congress.

Geographically, the district is thesecond-largest by land area, afterAlaska's at-large congressional district, and the largest by land area in thecontiguous United States. It is also thelargest district in the U.S. to not contain an entire state.

From 1913 to 1993,Montana had two congressional seats. From 1913 to 1919, those seats were elected statewide at-large on a general ticket. After 1919, however, the state was divided into geographical districts. The 2nd covered the eastern part of the state, includingBillings,Glendive,Miles City, and other towns. After 1993, the second seat was eliminated and the remaining seat was electedat-large.

After the release of the2020 United States census results, Montana regained its 2nd congressional district.^[3] On November 12, 2021, Montana's Districting and Apportionment Commission approved a new congressional map in which the 2nd congressional district would cover the eastern portion of Montana, in a configuration similar to the 1983–1993 map. However, the state capital,Helena, which had historically been in the 1st district, was drawn into the 2nd district.^[4]

Except for the city of Helena and someNative American areas likeBig Horn County and part of longtime nationalbellwetherBlaine County, the district is powerfully Republican. Overall, it is one of the most Republican district in the West, with aCook Partisan Voting Index of R+15, and it voted forDonald Trump by nearly 27 percentage points in the2020 presidential election.

The second district includes all of the following counties, with the exception ofPondera, which it shares with the1st. Pondera County communities in the 1st district includeBrady,Conrad, andMidway Colony.^[7]
