Phalarodon is an extinct genus of mixosaurid ichthyosaur known from the Middle Triassic (247.2-242.0 million years ago). Its name is derived from the Greek φάλαρα (phálara) ("boss on the cheek plate of a helmet") and odon ("tooth"). The genus has had a tumultuous history since its classification in 1910, with different workers describing species under different genera or declaring the genus to be a nomen dubium. Currently three species are recognized, but more have been identified in the past.
