Zeltnera davyi is a species of flowering plant in the gentian family known by the common name Davy's centaury.

[3] It is also found in the northern Mexican state of Baja California to some extent.

The inflorescence is a small, open array of flowers, some on very short pedicels.

Zeltnera davyi was scietifically described as a subspecies named Centaurium exaltatum var.

It was reevaluated as a species by LeRoy Abrams in 1951 and given its present name by Guilhem Mansion in 2004.
