Lupinus shockleyi, commonly known as the desert lupine and the purple desert lupine, is a species of flowering annual plant in the genus Lupinus (lupines) in the legume family Fabaceae. Native to southern California, southern Nevada, and northwestern Arizona, it can be found in the Mojave Desert. Standing at up to 30 cm (12 in) tall, L. shockleyi blooms from March to May with dark blue-purple petals on flowers which spiral around its inflorescence. It is a two-seeded plant, with seeds that feature a wrinkly texture.

The species was first described by the American botanist Sereno Watson in 1887. Among the specimens that Watson used for his description was one collected by William H. Shockley, a mining engineer who would collect plants while he worked in the region.
