Argonauta bottgeri, also known as Böttger's argonaut, is a species of pelagic octopus belonging to the genus Argonauta. The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell (hence the name paper nautilus). A. bottgeri is best known from the waters off southern and eastern Africa, although it has also been reported from other parts of the Indian Ocean and from the western Pacific Ocean. The locus classicus of A. bottgeri is Mozambique.
