Eriogonum coloradense is a species of flowering plant in the buckwheat family known by the common name Colorado buckwheat. It is endemic to Colorado in the United States. This species is a mat-forming herb growing just a few centimeters tall. The leaves are located around the base of the plant. They are up to 4 or 5 centimeters long and are mostly green on top with woolly undersides. The inflorescences are borne atop flowering stems reaching up to about 10 centimeters tall. The inflorescence is a cluster of tiny white to pink flowers. This species is most closely related to Eriogonum lonchophyllum, and some authors, including Eriogonum expert James Reveal, suspect it may be a form of that species.
