Pacifichelys is an extinct genus of sea turtle from the Middle Miocene of Peru (Pisco Formation) and California (Temblor Formation).

[1][2] It was first named by James F. Parham and Nicholas D. Pyenson in 2010, and the type species is Pacifichelys urbinai from Peru.

[2] A second species, P. hutchisoni, was reassigned from the genus Euclastes.

Like the living Ridley and loggerhead sea turtles, Pacifichelys was durophagous, consuming hard-shelled organisms with crushing jaws.
