Hackelia (stickseeds) is a genus of plants in the borage family, Boraginaceae. It includes 54 species found in North America, western South America, temperate Eurasia, and Australia.[1] 12 species are native to California.[2]

The genus was named after Josef Hackel, a Czech botanist. The common name, stickseed, refers to the tendency of the barbed nutlets to stick to animal fur.[3]
