Horkelia clevelandii is a species of flowering plant in the rose family known by the common name Cleveland's horkelia. It is native to the Peninsular Ranges of southern California and northern Baja California. This is a perennial herb forming clumps of long, fernlike leaves and erect stems. The leaves are up to 18 centimeters long and are made up of triangular to rounded leaflets, each toothed or lobed and covered in thin hairs. The narrow stems reach 10 to 50 centimeters in height and bear flower clusters of several flowers. Each flower has hairy, lance-shaped leaflets and pointed sepals. The narrow oval petals are white. The center of the flower contains ten stamens and up to 50 pistils.

There are many species of Horkelia in California, and the genus has undergone some taxonomic revision. For information regarding other species and varieties of Horkelia, please refer to Calflora.org or the Jepson Manual.
