Grata of Bergamo was an early 4th-century Italian saint and martyr who lived in Bergamo. As the daughter of the local rulers Lupo and Adelaide, she later converted her parents to Christianity and encouraged them to establish the city's cathedral. Following the death of her husband, a German king, she governed Bergamo with benevolence. She is remembered for her devotion to the faith, particularly her efforts to provide Christian burials for martyrs and her establishment of charitable institutions in her home city.
