Montana's 1st congressional district

Montana's 1st congressional district is a congressional district in the United States House of Representatives that was apportioned after the 2020 United States census. The first candidates ran in the 2022 elections for a seat in the 118th United States Congress.

This seat's current representative is Republican Ryan Zinke.

History
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, with the 1st district covering the western part of the state, including Missoula, Great Falls, Butte, and Helena. After 1993, the MT's 2nd congressional district was eliminated and the remaining seat was elected MT's at-large congressional district.

Following the release of the 2020 United States census results, Montana was once again split into two congressional districts. The reconstituted 1st district covers the western third of the state, in a configuration similar to the 1983–1993 map. However, Helena was drawn into the reconstituted 2nd district.
