Percnon gibbesi is a species of crab. It is one of at least two species commonly called Sally Lightfoot (the other being the semi-terrestrial Grapsus grapsus from the Pacific coast of the Americas) and is also referred to as the nimble spray crab or urchin crab. It has been described as the most invasive decapod species to enter the Mediterranean.
