The Uncompahgre fritillary is a species of butterfly in the family Nymphalidae. It is often considered as a subspecies of Boloria improba, the dingy fritillary. It is endemic to the United States. It was discovered above tree-line at Uncompahgre Peak, located in Hinsdale County, Colorado, USA in 1978 by Larry Gall, Felix Sperling, Scott Graham, Kathleen Shaw, and Wendy Roberts working out of the Rocky Mountain Biological Laboratory. It was thought to be on the edge of extinction, but a number of additional populations have been found and the early monitoring programs that detected small numbers were found to be inadequate. The population is still considered to be endangered.
