Elliot's storm petrel (Oceanites gracilis) is a species of seabird in the storm petrel family Oceanitidae. The species is also known as the white-vented storm petrel.

Despite considerable research, only one nest had ever been found prior to 2003, that being on the Isla Chungungo, off the coast of Chile. During a survey in 2002, about eleven nests were found in three crevices on this island, but it was also being used by nesting Humboldt penguins (Spheniscus humboldti) and there seemed to be very few suitable sites for the petrels to nest. Another possible breeding site may be inland in the Atacama Desert; a mummified chick, verified by DNA analysis, has been found in a crevice here, and signs of former activities in various...
