Pinnoctopus is a genus of octopuses in the family Octopodidae.
It is of doubtful validity.
ITIS treats Pinnoctopus as a synonym of Octopus Cuvier, 1797.
While the World Register of Marine Species treats it as a nomen dubium, has P. cordiformis as a species of doubtful validity and assigns P. kermadecensis to Octopus.
