Potentilla callida, commonly known as Tahquitz mousetail, is a rare species of flowering plant in the rose family.
The plant is endemic to the San Jacinto Mountains of Riverside County, California, where it is known from only two occurrences. The plant grows in cracks and crevices of granite mountain cliffs. It was named for Tahquitz Rock, a rock formation in its endemic range. The rock formation was named for the Native American spirit Tahquitz.
