Cordylanthus maritimus Chloropyron maritimum is a rare species of flowering plant in the family Orobanchaceae native to western North America.

It is native to the Western and Southwestern United States and northern Mexico, from southern Oregon to Baja California.

It is hemiparasitic, such that it is greenish and has chlorophyll but also parasitizes other plants by inserting haustoria into their roots to tap nutrients.

This plant grows in low clumps and has small, thick, gray-green hairy leaves often tinted with purple.

It erects an inflorescence several centimeters high which has many fuzz-covered white or cream club-shaped flowers with yellow or purplish tips.
