Hackelia sharsmithii is a species of flowering plant in the borage family known by the common name Sharsmith's stickseed.

It is native to the Sierra Nevada of California, where its range extends along ridges surrounding the intersection of Inyo County and Fresno and Tulare Counties, including Mount Whitney.

Most of the leaves are located around the base of the plant, reaching up to 14 centimeters long.

Leaves higher on the stem are shorter and narrower.

The hairy inflorescence is an open array of branches, each a coiling panicle of light blue flowers.
