Clarkia cylindrica is species of flowering plant in the evening primrose family known by the common name speckled fairyfan, or speckled clarkia. It is endemic to California, where it grows in the chaparral, woodlands and grassland of the coastal mountain ranges and Sierra Nevada foothills. This is an annual herb producing an erect stem to around half a meter in maximum height. Leaves are mainly linear in shape and up to six centimeters long.

The petals are intergrading shades of lavender, white, and magenta and they are often speckled with purple or pink. Beneath the petals are bright pink fused sepals.
