Flavius Arintheus (or Arinthaeus; died AD 378) was a Roman army officer who started his career in the middle ranks and rose to senior political and military positions. He served the emperors Constantius II, Julian, Jovian and Valens. In 372 he was appointed consul, alongside Domitius Modestus.
Arintheus served under Constantius during his campaign against the Alemanni, 354–5, under Julian in his Persian campaign, 363, and under Valens in the First Gothic War, 367–9, and Armenia, 370. He was one of the clique of senior officers who elected Jovian to the throne, and may have played a similar role in the election of Valentinian. He died in 378 while serving as magister peditum, one of the two most senior military positions of the Roman Empire.
