Solomonia Saburova was a 16th-century grand princess of Moscow and the wife of Grand Prince Vasili III. Born around 1490 to the nobleman Yury Konstantinovich Saburov, she married the monarch in 1505. Because she was unable to produce an heir, her marriage was annulled in 1525 with ecclesiastical approval. Following the divorce, she entered monastic life under the name Sophia. She spent her remaining years in Suzdal, where she lived as a nun until her death in 1542.
