The Kenai River is a river in the Kenai Peninsula of south central Alaska. It runs 82 miles (132 km) westward from Kenai Lake in the Kenai Mountains, through the Kenai National Wildlife Refuge and Skilak Lake to its outlet into the Cook Inlet of the Pacific Ocean near Kenai and Soldotna, Alaska. The Kenai River is the most popular sport fishing destination in Alaska, particularly for King or Chinook salmon.
