Sidalcea hickmanii is a species of flowering plant in the mallow family known generally by the common name chaparral checkerbloom.
Sidalcea hickmanii is endemic to California, where it grows in the Central Coast Ranges, the Transverse Ranges and parts of the northern coast. There are four subspecies, most of which are separated geographically. The plant grows in chaparral and other habitat, sometimes on serpentine soils.
This perennial herb produces a rough-haired stem up to a meter tall with a woody caudex at the base. The leaves have wide, fan-shaped blades which have rippled edges or divisions into narrow lobes. The inflorescence is an array of several racemes of flowers. Each has pinkish to purplish petals up to 2.5 centimeters long.
