Ocypode gaudichaudii, also known as the painted ghost crab or cart driver crab, is a species of crab found on Pacific beaches from El Salvador to Chile as well as on the Galápagos Islands. The species was first described by Henri Milne-Edwards and Hippolyte Lucas in 1843. They are diurnal crustaceans that display a red-orange color with sandy dots across the back of the carapace. In Peru, this crab is the host of the acanthocephalan parasite Neoandracantha peruensis.
