Marios Kyriazis (Greek: Μάριος Κυριαζής; born 11 March 1956) is a medical doctor and gerontologist.

[1] Applying the concept of hormesis on anti-ageing medicine, Kyriazis controversially suggested that leading a stressful, irregular and constantly stimulating lifestyle may be a way of reducing the impact of age-related dysfunction.

[5] The first public lecture was given at the University of London with support from the Wellcome Trust.

In 2001, in association with the Larnaca Municipality, he organised an exhibition on the medical history in Cyprus with the theme "Medicine in Ancient Kition and Old Larnaca",[citation needed] accompanied by a book on the matter with the same title.

[6] Following the tradition of other benefactors in the family (such as his grandfather Dr Neoclis Kyriazis and his great- uncle Damianos Kyriazis), in 2008 he founded the Kyriazis Medical Museum, a cultural charitable foundation aiming to safe keep old medical items and traditions of Cyprus, and to educate the public on the Cypriot Medical History.
