Centaurium davyi is a species of flowering plant in the gentian family known by the common name Davy's centaury.
The plant 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 sage scrub habitats on bluffs and dunes, and in coastal woodlands.
Centaurium davyi 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.
