Jujubinus pseudogravinae is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. It occurs in the Atlantic Ocean off the Azores, and the size of the shell varies between 3 mm and 7.5 mm.
Some consider this species a synonym of Jujubinus gravinae gravinae (Dautzenberg, Ph., 1881).
