Penstemon harringtonii is a species narrowly endemic to northwestern and north-central Colorado in the United States. Its range spans a 132 by 77 kilometers (82 by 48 mi) area on both sides of the Colorado River drainage in the Rocky Mountains. The species prefers sandy soil in the arid sagebrush steppe between elevations of 2,000 and 2,900 meters (6,400 and 9,400 ft). Plants can also be found in pinyon–juniper woodlands. P. harringtonii was recorded as found in Eagle, Grand, Routt, Summit counties in 1988; plants were later also found in Garfield and Pitkin counties. As of 2006, the entire population of an estimated 40,000 to 43,000 individuals was spread across 40 square kilometers (10,000 acres) of occupied habitat. As of 1999, Harrington's beardtongue was observed growing in substantial numbers in the medians of Interstate 70 near Vail, Colorado.
