Montana's at-large congressional district is a single congressional district that encompasses the entire state of Montana. This district is unique because it has only one representative in the U.S. House of Representatives, reflecting the state's relatively low population compared to other states. The at-large district was established after Montana gained statehood in 1889. Due to population changes, Montana lost and regained congressional seats over the years, but it has maintained its at-large status since 1993. The representative serves the interests of all Montanans in federal matters, including legislation and budget decisions.
