Gersemia juliepackardae is a species of soft coral in the family Nephtheidae.

The coral is named in honour of Julie Packard, the executive director of the Monterey Bay Aquarium, for "her dedication to ocean stewardship and conservation, and for elevating public awareness about the ocean environment.

"[2] Colonies of Gersemia juliepackardae have an upright main stem and are attached to the substrate by a holdfast.

[2] The holotype was collected in 2007 from Pioneer Seamount off the coast of central California, at a depth of approximately 1,000 m (3,281 ft).

Observations from a remotely operated underwater vehicle show that most specimens are attached to rock substrates singly, or in small groups, while some grow on dead and living sponges; these may be the first examples known where octocorals in the deep sea are living on sponges.
