Tus (Persian: توس‎‎ or Persian: طوس‎‎ Tus or Tuws), also spelled as Tous, Toos or Tūs, is an ancient city in Razavi Khorasan Province in Iran near Mashhad. To the ancient Greeks, it was known as Susia (Ancient Greek: Σούσια). It was captured by Alexander the Great in 330 BCE. It was also known as Tusa.

Tus was taken by the Umayyad caliph Abd al-Malik and remained under Umayyad control until 747, when a subordinate of Abu Muslim Khorasani defeated the Umayyad governor during the Abbasid Revolution. In 809, the Abbasid Caliph Harun al-Rashid fell ill and died in Tus, on his way to solve the unrest in Khorasan. His grave is located in the region.

Tus was almost entirely destroyed by the Mongol conquests between 1220 and 1259.
