Omphalosaurus is an extinct genus of marine reptile from the Early Triassic of Spitsbergen.
Is has been considered an ichthyopterygian, however a study by Motani (2000) showed that it lacks the basal synapomorphies of Ichthyopterygia. As such, its exact position in the diapsid tree is currently unknown.
