Dahlella caldariensis is a species of leptostracan crustacean which lives on hydrothermal vents in the Pacific Ocean.

Dahlella may reach a length of 8.1 mm (0.32 in) from the base of the rostrum to the end of the abdomen. Much of the animal is covered by a large, hinged carapace. Dahlella can be distinguished from other animals in the same family by the presence of a row of denticles (small teeth) on the eyestalks, which it is believed are used to scrape surfaces for food. A similar character is found in Paranebalia (Paranebaliidae), but the form of the eyestalk is very different in the two taxa.

D. caldariensis has been recorded from a small number of sites around hydrothermal vents in the eastern Pacific Ocean near the Galápagos Islands and on the East Pacific Rise. It is one of the deepest-living species of Leptostraca, having been found at depths of over 2,300 m (7,500 ft).

The generic name Dahlella commemorates the biologist Erik Dahl of the University of Lund. The specific epithet comes from the Latin word meaning hot bath, and is a reference to the natural habitat of D. caldariensis.
