Vardan Mamikonian () (393 AD — 451 AD), also known as Saint Vardan (Սուրբ Վարդան Surb Vardan) was an Armenian military leader, a martyr and a saint of the Armenian Church. Vardan Mamikonian, a member of the Mamikonian family, is revered as one of the greatest military and spiritual leaders of Christian Armenia in the 5th century. Saint Vardan Day, usually in February (rarely at times in first week of March but always falling on a Thursday), is commemorated by churches in Armenia and the Armenian diaspora. He is considered a national hero. Major Armenian churches are named after Saint Vardan. A major equestrian statue representing him is found in the Armenian capital Yerevan.
