The Yukon River flows entirely within North America. It originates in the coastal mountains of northern British Columbia, Canada, traverses the Yukon Territory (giving the territory its name), crosses into Alaska, USA, and empties into the Bering Sea.
At 1,980 miles (3,190 km), it is the third-longest river in North America and a historic route for Indigenous peoples, Klondike gold rushers, and modern-day adventurers.
