The Soutzos or Soutsos (Romanian: Suţu or Sutzu) is a Greek Phanariote family which grew into prominence and power in Constantinople (present-day Istanbul) during the last centuries of Ottoman Empire and gave several short-reign hospodars to the Danubian Principalities, like Mihai Suţu, and his nephew Michael Soutzos (Mihail Suţu). The main branch of the above family is found now in Greece. One branch resides in Thessaly, in Central Greece, in Karditsa and nearby in the mountain village of Portitsa, where the family name was countrified into Tsioutsios. The family claims Byzantine roots, and there is reference to it in the Court of Constantine the Great.
