No US state borders Alaska. It’s one of two non-contiguous states (Hawaii is the other), separated from the rest of the country by a foreign nation. So if you came here for a list of neighboring states, the honest answer is a short one: there isn’t one.
But the why is the interesting part. Alaska shares a long land border with Canada and sits a stone’s throw from Russia across the water. Here’s exactly who Alaska touches, which US state comes closest, and why you can’t drive from Seattle to Anchorage without crossing into another country first.

The Short Answer {#the-short-answer}
No US state borders Alaska. Alaska is geographically detached from the contiguous 48 states. Its only land border is with Canada — specifically the province of British Columbia and the territory of Yukon. To the west, the Bering Strait separates it from Russia by sea.
| Neighbor | Type of border | Distance / length |
|---|---|---|
| Canada (British Columbia & Yukon) | Land | ~1,540 miles |
| Russia (across Bering Strait) | Maritime | ~55 miles strait; 2.4 miles island-to-island |
| Washington (nearest US state) | None — separated by Canada | ~500 miles away |
Why No State Borders Alaska {#why-no-state-borders-alaska}
Pull up a map of North America and the reason is obvious. Alaska sits in the far northwest corner of the continent, and the entire western flank of Canada — roughly 500 miles of British Columbia and Yukon — wedges between it and Washington State, the northwesternmost state in the Lower 48.
When the US bought Alaska from Russia in 1867 for $7.2 million, it acquired a territory that simply didn’t connect to any existing state. That gap never closed. Canada owns the land in between, and it always has. A “non-contiguous” state is one that doesn’t share a border with the main body of the country, and Alaska is the textbook case. If you’re curious how the rest of the map fits together, our breakdown of US states organized by their bordering states shows just how unusual Alaska’s isolation really is.
This is also why the Alaska Highway exists. Built in 1942, it runs more than 1,300 miles through Canada because there’s no other way to drive there from the Lower 48. You leave the US, spend the better part of two days crossing British Columbia and Yukon, and re-enter the US at the Alaskan border.
Alaska’s Real Neighbors: Canada and Russia {#alaskas-real-neighbors}
Alaska doesn’t border states, but it borders countries — two of them.
Canada is the land neighbor. The boundary stretches about 1,540 miles, touching British Columbia along the southeastern panhandle and Yukon up the eastern edge. It’s a real, drivable, customs-and-passport border. This is the answer to the common follow-up question of whether Alaska borders Canada: yes, and it’s the only land border Alaska has. Alaska is also one of the 13 states that share a border with Canada — the only one that does so without touching the rest of the country.
Russia is the maritime neighbor. The two countries face each other across the Bering Strait, and at their closest point they’re shockingly near — more on that below. There’s no bridge and no ferry across the strait, but the international boundary between the US and Russia runs right down the middle of it.
The Closest US State {#the-closest-us-state}
Washington. The northwest tip of Washington State is the nearest point in the contiguous US to Alaska, roughly 500 miles away as the crow flies — with all of coastal British Columbia filling the gap.
That distance is why Alaska feels like its own world even to other Americans. You can’t road-trip there without a passport. The most common ways in are a flight to Anchorage or Fairbanks, the Alaska Marine Highway ferry system up the Inside Passage, or that long haul up the Alaska Highway through Canada.
How Close Is Alaska to Russia? {#how-close-is-alaska-to-russia}
Closer than most people guess. The Bering Strait is only about 55 miles wide at its narrowest. But the real headline lives in the middle of it: the Diomede Islands.
Big Diomede belongs to Russia. Little Diomede belongs to the United States. They sit about 2.4 miles apart — and the International Date Line runs between them, which means Big Diomede is nearly a full day ahead. Locals on Little Diomede sometimes call its Russian neighbor “Tomorrow Island.” Stand on the American island on a clear day and you can see Russia. Not metaphorically. Actually. The communities on the Russian side are home to some of the Indigenous languages of Russia that share deep cultural roots with Alaska Native peoples across the strait.
In winter the strait can freeze over, and the gap between the two Diomedes occasionally becomes a stretch of ice. The National Park Service notes that the two islands sit just over two miles apart, a remnant of the land bridge that once connected the two continents entirely.
Exclave, Not Enclave {#exclave-not-enclave}
People mix these two up constantly, so here’s the clean version.
An exclave is a piece of a country that’s separated from the main body and surrounded (at least partly) by other territory. An enclave is a territory completely surrounded by a single other country.
Alaska is an exclave of the United States — cut off from the Lower 48 by Canada, but not fully enclosed by it, since it also has its own coastline and that maritime line with Russia. It’s not an enclave, because no single foreign country surrounds it.
If you want the trivia-night-winning phrasing: Alaska is the largest state by area, the least densely populated, and the only US state you have to leave the country to reach by road.
Quick FAQ {#quick-faq}
What states border Alaska? None. No US state shares a border with Alaska. It’s separated from the contiguous United States by Canada.
What country borders Alaska? Canada borders Alaska by land (British Columbia and Yukon), and Russia is its maritime neighbor across the Bering Strait.
What is the closest state to Alaska? Washington, about 500 miles away, with coastal British Columbia in between.
Can you drive to Alaska from the Lower 48? Yes, but only by driving through Canada on the Alaska Highway. You’ll cross the US–Canada border twice and need a passport.
Does Alaska border Canada? Yes. The Alaska–Canada land border runs about 1,540 miles along British Columbia and Yukon. It’s Alaska’s only land border.
How far is Alaska from Russia? The Bering Strait is roughly 55 miles wide, but the US and Russian Diomede Islands sit only about 2.4 miles apart.
