Kyriakos Matsis (Κυριάκος Μάτσης) (23 January 1926[1] - 19 November 1958[2]) was a Greek Cypriot guerrilla and member of EOKA (Ethniki Organosis Kyprion Agoniston).
He received his secondary education at the Famagusta gymnasium and, in 1946, enrolled at the University of Thessaloniki in Greece, from which he obtained his agricultural studies degree.
In 1948, he testified as a defence witness in the trial of Yannakis Drousiotis, a Cypriot communist captured by the Army, stating in court that the defendant's motives were "pure" and "not traitorous."
He managed to escape, and fled onto the Pendadactylos area, where he continued working for EOKA, taking up command of military operations in the Kyrenia region.
John Profumo, the junior Office minister, oversaw a special executive order to speed up the flow of military material to the island.
