Red Canyon is a canyon located in Fremont County, Wyoming in the United States of America. The uplift of the nearby Wind River Range 60 million years ago exposed sedimentary rocks that were eroded by streams. The canyon exposes a number of geologic formations including the Phosphoria Formation from the Permian Period and the Chugwater Formation from the Triassic Period. Oxidized iron deposits in the rocks give the canyon its name. Red Canyon Creek drains the canyon and feeds into the Little Popo Agie River at the northern end.
