Sufax, Syphax, Sufaqs or Sophax (Ancient Greek: Σόφακος Sophaxus) was a hero or demigod from the Berber and Greek mythologies.^[1]

According to the myth, Sufax was the son of goddess Tinjis from her second marriage to demigod Heracles, and the grandson of Zeus and mortal Alcmene.^[2][3] His half-sister was likely Iphinoe, and his half-brother (and possible half-nephew) was Palaemon, son of Iphinoe and Heracles.

Sufax replaced his mother's first husband Antaeus as a guard of the country of the Berbers (or Imazighen).^[4][5] He is said to be the founder of Tangier in memory to his mother.

According to the Berber mythology, many of the Berber kings are descendants of Sufax, who defended their lands. He had a son, Diodorus, who reigned over many North African Berber tribes with the help of the Olympians.^[6] According to the ancient Greek historian Plutarch, many of the myths were created in order to give credits to the Numidian king Juba II who considered himself a descendant of Diodorus and Hercules.
