Which river is the longest in Alaska?

The Yukon River is the longest river in Alaska, measuring approximately 1,979 miles in total length. This river begins in Canada, flowing through Alaska before eventually emptying into the Bering Sea. Its significant length and volume make it one of the major rivers of North America, not just Alaska.

The Kuskokwim River, while substantial, is shorter at about 702 miles. The Kenai River, known for its recreational activities and salmon runs, spans only about 82 miles, and the Susitna River is roughly 313 miles long. Thus, while each of these rivers has its unique features and importance, it is the Yukon River that holds the title of the longest river in Alaska.
