Ceanothus pauciflorus (Mojave ceanothus) is a native California shrub in the Rhamnaceae family, recognized by white flowers and gray-white fuzzy twigs.

Mojave ceanothus is a California native shrub found in southern Sierra Nevada, Tehachapi, Transverse, Peninsular, and eastern Sierra Nevada, and Desert Mountains in chaparral, woodland, and conifer forest at elevations of 550 to 2,600 meters. Flowering from March to May, this plant produces white flowers in compact umbel-like clusters about 1 to 1.5 centimeters long. Growing 0.8 to 2 meters tall with ascending to erect stems that are intricately branched and covered in pale gray to whitish, dense short hairs, the shrub forms an open, distinctive shape. Its opposite, evergreen leaves are oblanceolate to nearly round, 5 to 20 millimeters long, gray-green to yellow-green, with a concave upper surface and occasionally 3 to 5 sharp teeth near the tip. The fruit is approximately 3 to 5 millimeters wide with subtle ridges and minimal to no horns.
