Álvar García de Santa María (1370 - 1460) was a Spanish historian and Jewish convert to Roman Catholicism during the late Middle Ages. He was born in 1370 into a prominent Castilian Jewish family, but converted in 1390 at the time of evangelization of the Jewish community by St. Vincent Ferrer. His brother Pablo García de Santa María also converted and later became Bishop of Burgos, as did Álvar's nephew Alphonso de Cartagena, another Jewish convert.
