The central Colorado volcanic field is a volcanic field in Park County, Colorado. It is located in the southern Rocky Mountains and covered a roughly triangular area centered on the Thirtynine Mile volcanic area and extending from the Sawatch Range southeast to the northern Sangre de Christo Range and the Wet Mountains and northeast to the southern Front Range south of Denver. The area covered by the volcanic products of the eruptions included some 22,000 km2 produced by at least ten volcanic centers or calderas. The field overlaps the San Juan volcanic field to the west. The volcanic products date from late Eocene to Oligocene (38–29 Ma).
