The Porcupine River (Ch’ôonjik in Gwich’in) is a tributary of the Yukon River in Canada and the United States. It begins in the Ogilvie Mountains north of Dawson City, in the Yukon territory of Canada. From there it flows north through the community of Old Crow, veers southwest into the U.S. state of Alaska, and enters the larger river at Fort Yukon. It derives its name from the Gwich'in word for the river, Ch'oonjik, or "Porcupine Quill River".
