John Athalarichos (Greek: Ἰωάννης Ἀθαλάριχος), also spelled as Atalarichos, Athalaric, and At'alarik, was an illegitimate son of the 7th century Byzantine Emperor Heraclius. In 637, he was alleged to have taken part in a plot to overthrow Heraclius and seize the throne.
Athalarichos first appears in 622, when he was sent, along with Heraclius' nephew Stephen and John, the illegitimate son of the patrician Bonus, as a hostage to the Avars to cement a peace agreement.
In 635 or 637, some Armenian figures, at the time very influential in Constantinople, felt their interests would be better served under a new Emperor. Their candidate to replace Heraclius was Athalarichos. Also involved were the curopalates Varaztirots, son of Smbat Bagratuni; David Saharuni, Athalarichos' cousin; and Heraclius' nephew, the magister Theodore. Varaztirots pushed for a bloodless coup, in which the Emperor would be forced into exile.
The scheme was never executed, as an informer in the conspirators told the imperial court that Athalarichos was planning a coup attempt. Once Heraclius confirmed the story, he ordered the arrest of everyone involved. His advisers recommended the plotters be executed, but Heraclius was quoted by the historian Sebeos as saying, "Since you did as you did with regard to me and did not want to dip your hand into my blood and the blood of my sons, I shall not reach for you and your sons. Go where I order you, and I will have mercy upon you."
While he did spare their lives, Heraclius ordered the amputation of each plotter's nose and hands. In addition to being thus mutilated, Athalarichos was exiled to Prinkipo, one of the Princes' Islands. Theodore received the same treatment, but was sent to Gaudomelete (possibly modern day Gozo Island) with additional instructions to cut off one leg.
