Calliotropis oros is a species of sea snail, a marine gastropod mollusk in the family Eucyclidae and of small deep-water vetigastropod described by Claude Vilvens in 2007 from the southwest Pacific. Vilvens placed it within Calliotropis (then treated in Calliotropinae), and subsequent databases list it in family Eucyclidae/Calliotropidae within superfamily Seguenzioidea (taxonomy in this group has shifted over time).
The length of the shell is between 4 and 6 mm.
This marine species occurs off Fiji and New Caledonia.
