Anna Koltovskaya was a 16th-century Russian tsarina and the fourth wife of Ivan IV, also known as Ivan the Terrible. Born around 1552 to the courtier Alexei Koltovski, she married the tsar in 1572 at the Assumption Church. Following her marriage, the couple traveled to Novgorod for their honeymoon. Due to her inability to conceive children, she was eventually repudiated by the tsar. She later entered the Vedenski-Tikhvinski convent, where she lived as a nun under the name Daria until her death in 1626.
