The Herron River (Lower Tanana: K'otaal No’ or Tsatasronik) is a 48-mile (77 km) tributary of the Foraker River in central Alaska in the United States. It drains an area on the north slope of the Alaska Range on the south edge of the Tanana Valley southwest of Fairbanks. The river issues from Herron Glacier in the northern Alaska Range in Denali National Park and Preserve, northwest of Mount Foraker. It flows through the tundra to the north of the Alaska range in a generally northwest direction, forming part of the boundary between national park lands and national preserve lands.
