Centaurium davyi is a species of flowering plant in the gentian family known by the common name Davy's centaury. It is endemic to California, where it is known from the coastline around the San Francisco Bay Area and areas north, as well as from Santa Cruz Island, one of the Channel Islands. It grows in moist coastal habitat, such as bluffs, dunes, and forest. It is an annual herb not exceeding about 25 centimeters in height, with oval leaves under 2 centimeters long. The inflorescence is a small, open array of flowers, some on very short pedicels. Each flower has generally five overlapping corolla lobes, each only a few millimeters in length, usually pink or partially pink in color.
