Calponia harrisonfordi is a species of spider discovered in 1993 by the arachnologist Norman I. Platnick, and named after the film actor Harrison Ford to thank him for narrating a documentary for the Natural History Museum in London. It is the only species of the genus Calponia, and is one of the most primitive members of the Caponiidae family.
C. harrisonfordi is found in California in the United States. Unlike most members of its family, C. harrisonfordi retains all eight eyes and has few of the family's characteristic distal leg segment modifications. It is roughly 5 millimetres (0.20 in) in length. Much of its physiology is not well understood, but it is thought to eat other spiders.
