Pediocactus winkleri, commonly known as Winkler's cactus or Winkler's pincushion cactus, is a small cactus found only in Emery County, Utah or Wayne County, Utah in eastern Utah.
The cactus is shaped like a small, ribbed, ball. There are no central spines, and 9-14 short radial spines, each 1.5-4 mm long. The flowers range from peach to pink in color. They are cold hardy and are native to high altitude sandy hilltops and slopes.
This cactus is closely related to Pediocactus bradyi, and in the past has been characterized as either a variety or a subspecies of P. bradyi. It is listed as a threatened species under the name P. bradyi subsp. winkleri.
P. winkleri was listed as "threatened" under the Endangered Species Act on August 20, 1998, and it is currently a federally listed species and therefore covered under the provisions of the Act.
