America's Largest Congressional District: Alaska's At-Large Seat

The largest U.S. congressional district by area is Alaska's At-Large District. It encompasses the entire state—over 663,000 square miles, larger than Texas. Despite its vastness, the district's population is roughly 739,000 (similar to North Dakota). Since 1973, it has been represented by Republican Don Young (until his 2022 passing) and subsequently by Mary Peltola (Democrat) after a special election.
