Car or Kar (Greek: Κάρ) is a name in Greek mythology that refers to two characters who may or may not be one and the same.
The name "Car" is unrelated to the English word "car" (vehicle).
According to Pausanias, Car was the king of Megara and the son of Phoroneus (and Cerdo). His tomb was located on the road from Megara to Corinth. The acropolis at Megara derived its name Caria from him.
Herodotus mentions a (probably) different Car, brother of Lydus and Mysus; the three brothers were believed to have been the ancestral heroes and eponyms of the Carians, the Lydians and the Mysians respectively. This Car was credited by Pliny the Elder with inventing the auspicia.
Car was also said to have founded the city Alabanda, which he named after Alabandus, his son by Callirhoe (the daughter of the river god Maeander). In turn, Alabandus's name is said to have been chosen in commemoration of his Car's victory in a horse fight— according to the scholar Stephanus of Byzantium, "Alabandos" was the Carian word for "winner in a horse fight". Another son of Car, Idrieus, had the city Idrias named after himself.
The tomb of Car was in the Carian city Souangela, giving that city its name— according to Stephanus, "Souangela" meant "tomb of the king" in Carian.
