Timarchus or Timarch was a Greek noble and a satrap of the Seleucid Empire during the reign of his ally King Antiochus IV Epiphanes. After Antiochus IV's death, he styled himself an independent ruler in his domain in the Persian east of the Empire from around 163–160 BC, and may have even sought to entirely usurp leadership of the entire empire. He gained an alliance with the Roman Republic, which sought to weaken the Seleucid Empire by promoting internal divisions; both Rome and Timarchus distrusted the new king Demetrius I. Demetrius rode east and defeated Timarchus in 160 BC, ending his short reign.
