Bertha of Artois was a Frankish abbess of noble lineage who lived during the 7th and 8th centuries. Born to Count Rigobert and Ursana, a daughter of the King of Kent, she married a relative of the king named Siegfried. Following her husband's death in 672, she dedicated her life to religious service. She eventually established a convent in Blangy, Artois, where she served as abbess alongside her daughters before retiring to a life of prayerful seclusion.
