Giovanni Andrea I Angelo Flavio Comneno (Latin: Joannes Andreas Angelus Flavius Comnenus; 20 March 1569 – December 1634) was the Grand Master of the Constantinian Order of Saint George from 1592 to 1623 and from 1627 to 1634. In addition to the position of grand master, Giovanni Andrea also claimed the titles "Prince of Macedonia" and "Duke and Count of Drivasto and Durazzo". Giovanni Andrea oversaw a period of internationalization of the Constantinian Order, and despite repeated challenges to his position managed to maintain the widespread recognition of his order and family.
