The Hogatza River (Koyukon:àHÃÂgaadzaat NoâÂÂ; Iñupiaq: Kuuáuqpak or Haukaatchiatnaaq) is a tributary of the Koyukuk River in the U.S. state of Alaska. Beginning in the Gates of the Arctic National Park and Preserve, it flows generally southwest to meet the larger river west of Hughes. The river's name is from the Koyukon language, but the meaning is uncertain.
