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.
