Which strait separates Russia and Alaska?

The Bering Strait is a strait of the Pacific ocean, which borders with the Arctic ocean to north. It is located between Russia and the United States.

Named after Vitus Bering, a Danish explorer in the service of the Russian Empire, it lies slightly south of the Arctic Circle.

The Strait has been the subject of the scientific hypothesis that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels exposed a wide stretch of the sea floor.

This view of how Paleo-Indians entered America has been the dominant one for several decades and continues to be the most accepted one. Numerous successful crossings without the use of a boat have also been recorded since at least the early 20th century.
