Alaska's Borders: No US States—Only Canada and Russia
Alaska does not border any other US state. It is separated from the contiguous "Lower 48" by Canada.
Land Borders
- East: Canada (Yukon Territory and British Columbia) — ~1,538 mi (2,475 km).
Maritime Border
- West (Bering Strait): Russia (Chukotka Autonomous Okrug) — ~55 mi (88 km) at narrowest point (between Little Diomede [US] and Big Diomede [Russia] islands).
Maritime Boundaries
- Arctic Ocean (north)
- Bering Sea (west/southwest)
- Gulf of Alaska / Pacific Ocean (south)
Key Fact
Alaska is one of only two US states that border no other state (the other is Hawaii). It is an exclave of the United States.
