King Sanatruces of Parthia (also Sinatruces or Sanatruk) ruled the Parthian Empire from c. 77 to c. 70 BC. In the troubled times after the death of Mithridates II in c. 88 BC he was made king by the Sacaraucae , a Mongolian tribe who had invaded Iran in about 77 BC. He was eighty years old and reigned seven years; his successor was his son Phraates III.

Another Sanatruces (Sanatrucius), the son of Mithridates IV is mentioned as an ephemeral Parthian king in AD 115 by John Malalas, in his Chronographia.
