Leptosiphon acicularis (syn. Linanthus acicularis) is a species of flowering plant in the phlox family known by the common name bristly linanthus.
It is endemic to northern California, where it is known mainly from the San Francisco Bay Area north into the North Coast Ranges. It is a member of the flora in chaparral, woodland, and other local habitat.
This is an annual herb producing a hairy stem no more than about 15 centimeters tall. The oppositely arranged leaves are each divided into very narrow bristlelike lobes up to a centimeter long. The tip of the stem is occupied by an inflorescence of one or more tiny yellow flowers surrounded by many needlelike sepals.
