"Gripper." A giantess, daughter of Geirröðr, and the sister of Gjálp. In Þórsdrápa, the sisters hide beneath a chair and when Thor sits down, they lift the seat up towards the roof, intending to crush him. Thor thrusts his staff Gríðarvölr up against the rafters and pushes back hard, and breaks both their backs.

In Völuspá hin skamma, Greip is mentioned as one of nine giant maidens who bore a mighty son, possibly Heimdallr. Her name is not found among the giantesses in the Nafnaþulur.
