Georgios Sachtouris (Greek: Γεώργιος Σαχτούρης, 1783–1841) was a Hydriot ship captain and a leading admiral of the Greek War of Independence. Sachtouris was born in Hydra in 1796 to a family of Arvanite origin. Like most of its population he engaged in maritime commerce. Following the outbreak of the Greek War of Independence, he became a leading commander of the Hydriot ships, and participated in the naval battles of Patras, Spetses, Samos, Gerontas, and others, as well as in the failed raid on Alexandria. Governor Ioannis Kapodistrias appointed him commander of the Messenian squadron, but soon he joined the opposition forces against the Governor.
