HMS Hyacinth was a Flower-class corvette of the Royal Navy. She served during the Second World War and achieved three victories over enemy submarines in a highly successful career. Only Sunflower managed to repeat such success among her sister ships. She went on to serve in the Royal Hellenic Navy as RHNS Apostolis (Greek: ΒΠ Αποστόλης), was returned to the Royal Navy in 1952 and scrapped in the same year.
