Argonauta pacifica, also known as the Pacific argonaut, is a species of pelagic octopus.

[1] A. pacifica seems to have a relatively limited distribution, being confined to the waters surrounding western Mexico, and in particular the Gulf of California.

For this reason, it is considered one of the rarest of the Argonauta species, along with A. cornuta and A. nouryi.

Further research is needed to determine whether it is a valid species or a synonym of another taxon.

The type specimen of A. pacifica was collected off the coast of California and is deposited at the National Museum of Natural History in Washington, D.C.[2]
