Wyoming has a single at-large congressional district, meaning one representative serves the entire state in the U.S. House of Representatives. As one of the least populous states, Wyoming does not have enough residents to warrant multiple districts under the current apportionment.
Wyoming’s single seat covers all of its about 577,000 residents counted in the 2020 Census, so every voter in the state shares the same U.S. House member. The at-large seat is on the ballot every two years, next on November 3, 2026, and the winner represents the whole state rather than one district within it.
Wyoming is represented by one at-large member because its population supports just a single seat, and the reapportionment that followed the 2020 Census kept it at one. Unlike states with several districts, Wyoming has no congressional lines to redraw after each census, so the boundary of its district is simply the state border. To confirm you live in Wyoming’s district, use the ZIP code lookup on our home page.
Wyoming’s at-large seat is currently held by Harriet Hageman (R). All House seats are up for election on November 3, 2026.
Wyoming is also represented in the U.S. Senate by Cynthia Lummis (R) and John Barrasso (R).
