Anna of Euphrania (18 August 1610 - 24 December 1665) was Empress consort of Diadochia, regent for her son, Eric III of Diadochia, and a Euphran Infanta by birth. During her regency (1647-1659), Chartophylax Angelos served as Diadochia's chief minister. Accounts of Diadochian Imperial court life during her lifetime describe her difficult marital relations with her husband Constantine VI, her closeness and affection for her eldest son Eric III, her disapproval of her son's marital infidelity to her niece Sophia Theresa, and her overall virtuous nature.
